Hundreds of global researchers, including University of Zurich, are planning the most sensitive dark matter detector ever built.
Immagine: XENON experimentThe XENON/DARWIN and LUX-ZEPLIN collaborations have now joined forces to work together on the design, construction, and operation of a new, single, multi-tonne scale xenon observatory to explore dark matter. The detector will be highly sensitive to a wide range of proposed dark matter particles and their interactions with visible matter. Over the last 20+ years, experiments using liquefied xenon targets have delivered world-leading results in the global quest for direct dark matter detection. This next-generation detector aims to continue the pursuit.

The newly opened Science Exploratorium of the University of Zurich hosts temporary exhibitions in which researchers share their enthusiasm for their research topics.
The European Research Centre for Particle Physics (CERN) in Geneva is currently working on making the measurement data from four large-scale experiments available to the public via internet. This form of 'open science' benefits particle physicists around the globe, but also students or high school students - for example in Switzerland.
This public symposium is dedicated to the physicist Wilhelm Conrad Röntgen (1845 - 1923) and his vibrant legacy today. Röntgen studied mechanical engineering at the ETH Zürich and obtained his PhD in physics in 1869 from the University of Zürich. In 2020 his 175th birthday and the 125th anniversary of his discovery of X-rays should have been celebrated, but the event had to be shifted to 2021 due to the pandemic.

The Trust Science pledge is a worldwide campaign to promote support for the scientific process and to acknowledge the many benefits of science for society.
At the beginning of April, the US research laboratory Fermilab published a new result for the magnetic dipole moment of the muon. The result caused a broad media response because it deviates from the theoretical predictions and thus questions the previous understanding of the laws of nature. Researchers from the Albert Einstein Center for Fundamental Physics (AEC) at the University of Bern were involved in the theoretical predictions. Prof. Martin Hoferichter, theoretical physicist at the AEC, explains the background.
In Italy, female high school graduates choose to study physics much more naturally than it has been the case in Switzerland so far. Ilaria Zardo was one of these young Italian women who first became enthusiastic about studying physics and later about academic research. Today, as a professor at the University of Basel, she and her research group study heat flows at the nanoscale level.
When people talk about CERN, they inevitably think of the large-scale experiments at the Large Hadron Collider (LHC). But the European Laboratory for Particle Physics has even more to offer: A small but powerful experiment called FASER is currently being assembled at CERN, involving research teams led by Geneva physics professors Anna Sfyrla and Giuseppe Iacobucci and by Bern physics professor Akitaka Ariga. FASER proves: Even comparatively inexpensive experiments have the potential for groundbreaking scientific findings.
Almost ten years ago, the European Laboratory for Particle Physics (CERN) made headlines with the discovery of the Higgs particle. These days, the LHCb experiment at CERN has published results that also have the makings of a real scientific sensation: studies of the so-called beauty quark suggest that there could be a fifth, super-weak force in addition to the four known forces of nature (electromagnetism, gravitation, strong and weak interaction). However, CERN researchers still have a lot of work ahead of them to confirm this spectacular hypothesis. At the forefront: particle physicists from the University of Zurich and EPF Lausanne
Prima di arrivare alla pensione nel 2017, Martin Pohl è stato professore di fisica all'Università di Ginevra e ha lavorato a progetti di ricerca sulla fisica delle particelle per quasi mezzo secolo. Attingendo a questa ricchezza di esperienza, è stato scritto un libro in cui Pohl traccia consapevolmente i filoni evolutivi di questa disciplina fondamentale. Il culmine è il "Modello Standard" della fisica delle particelle - per Pohl un punto culminante scientifico e un peso allo stesso tempo.

This community roadmap summarizes a survey of the Swiss large-scale infrastructure requirements in the broad field of photon science for the years 2025–2028, drawing from the current situation both in Switzerland and abroad. The Swiss Society for Photon Science (SSPh) collected the scientific visions and compiled the needs of the community of photon science, which encompasses all research areas that work to generate, manipulate and detect photons or use them to investigate or control complex assemblies of matter.
This community roadmap presents the visions for future research in particle and astroparticle physics in Switzerland and formulates the needs of these fields in terms of research infrastructure in the years 2025-2028 and beyond. It was established under the auspices of the Swiss Institute of Particle Physics (CHIPP), which issued its first roadmap already in 2004 and conducted dedicated roadmap-planning workshops in 2018 and 2020.
This community roadmap presents a broad overview of the current status of neutron science in Switzerland and derives a set of recommendations for future developments. It is the result of a community effort led by the Swiss Neutron Science Society (SNSS) with the main objectives to survey and analyse the unique contributions that neutron probes provide across scientific and technological fields and disciplines; and provisions needed to ensure continuing and sustainable success.
Swiss Particle Physics researchers are very proud to announce that UZH people worked directly on this measurement and had a leading role on this analysis, EPFL and UZH are very prominent in LHCb in both analysis and hardware.

The technical know-how that physicists use in research could soon serve in the fight against the COVID-19 pandemic. An international team of scientists with strong Swiss participation has developed a ventilator in record time that could help in the future against lung diseases like Corona, especially in countries with a precarious medical infrastructure.
In the laboratories of modern physics the elementary components of matter are studied. To do this, scientists sometimes build artificial atoms to help them understand the laws of matter. A research team at the Paul Scherrer Institute (Villigen/AG) uses a specifically modified helium atom to determine the exact mass and other properties of pions. Pions could help to understand more precisely where atomic nuclei get their mass from.

Claudia Merlassino was born in Genoa, studied physics in Milan and completed her doctorate at the University of Bern in October 2019, since then she has been doing research at Oxford University in the UK. At the age of 28, the Italian experimental physicist has already made a remarkable journey as a researcher. She is now receiving the PhD prize in Swiss particle physics - among other things for her findings in the context of the most massive of all elementary particles.
Executive summary of an analysis prepared by the Centre for Economics and Business Research (Cebr) for the European Physical Society (EPS)
On June 19th CERN Council adopted the update of the "European Strategy for Particle Physics 2020". This document updates an earlier strategy paper that was adopted by the Council in 2013, just after the Higgs discovery in 2012. It identifies the medium and long-term priorities of fundamental research in particle physics and thus forms an important basis for the construction of the European research infrastructure. The implications of this strategy update for Swiss particle physics are answered by Rainer Wallny, Professor of Particle Physics at ETH Zurich and President of the Swiss Institute of Particle Physics (CHIPP), the umbrella organisation of Swiss particle physics.
The delta+ is a type of baryon, the family of sub-atomic particles to which the more well-known proton and neutron belong. A team of physics enthusiasts at the International School of Geneva is working intensively on these extremely unstable elementary particles. In September they will travel to Hamburg for an experiment at the renowned particle physics research institute DESY. They owe this extraordinary research trip to winning this year's “Beamline for Schools” (BL4S) competition at CERN.

When analyzing data from the XENON1T detector for dark matter, a signal excess was observed. The UZH researchers do not yet know for sure where this unexpected signal comes from. They say the origins could be relatively banal, but they could also indicate the existence of new particles or hitherto unknown properties of neutrinos.
To recognise the International Day of Light 2020 and the 60th anniversary of the laser, the Swiss Physical Society (SPS) publishes a detailed report by René Salathé (EPFL) to record the development and milestones in laser science from 1960 to 1980 in Switzerland.
This media update is part of a series related to the 2020 Large Hadron Collider Physics conference, which took place from 25 to 30 May 2020. Originally planned to take place in Paris, the conference was held entirely online due to the COVID-19 pandemic.

In deep underground tunnels of former mines near the Japanese Alps, teams of scientists with Swiss participation are researching various types of elementary particles. Over the next few years, powerful research instruments will be put into operation with which scientists want to discover the nature of neutrinos. The hoped-for results could lead to solving of deep puzzles in our understanding of the universe.
Nessuna particella elementare attraversa più frequentemente l’universo degli schivi neutrini. Le ricerche delle piccolissime particelle quasi senza massa è al centro dell’odierna fisica delle particelle elementari. Probabilmente il contributo più importante degli ultimi vent’anni alla conoscenza del neutrino lo dobbiamo al rivelatore giapponese Super-Kamiokande in cui diversi gruppi di ricercatori Svizzeri sono coinvolti. Una visita alle montagne in Giappone.
Pickel, Schaufel und Spatel gehören zwar noch immer zur archäologischen Feldausrüstung, immer öfter kommen aber bereits im Feld oder spätestens bei der Auswertung im Büro High-Tech Geräte zum Einsatz. Tragbare Röntgenfluoreszenz-Analysatoren sind ein Beispiel solcher Geräte, die zur grossen Freude archäologischer Konservatoren zerstörungsfreie Analysen ermöglichen.
Graben oder nicht graben? Das ist oft die Frage! Die Entscheidung müssen Archäologen aber nicht dem Zufall überlassen. Geophysikalische Prospektionen und die Fernerkundung erlauben sehr weit gehende Einsichten in den Untergrund, bevor die erste Schaufel Erdreich bewegt wird. Die dadurch gewonnenen digitalen Daten bilden die ideale Grundlage, um einen antiken Fundort durch gezieltes Anlegen von Grabungsschnitten möglichst detailliert zu erkunden.
Wollen Archäologen ohne zu graben den Untergrund erforschen, dann greifen sie zu geophysikalischen Methoden. Bei Luftbildauswertungen und elektrischen Widerstandsmessungen in Studen kam Erstaunliches zu Tage – aber auch die Erkenntnis, dass ein Grossteil des römischen Vicus undokumentiert dem Kiesabbau zum Opfer gefallen ist.
Neutrinos are ubiquitous yet elusive particles that could shed light on the early evolution of the universe. As one of the world’s major laboratories for neutrino physics, Fermilab partners with leading organizations around the globe to get a firmer grasp on these subtle particles.
The two researchers from the Astronomical Observatory of the University of Geneva share this extraordinary distinction with James Peebles, Professor Emeritus at Princeton University in the United States.

A labyrinth of mirrors, a shiny pot, countless cables and digital displays. Visiting Matteo Fadel at his workplace at the University of Basel, he first takes us to the laboratory where he tracks strange quantum phenomena. Somewhere in the midst of all this apparatus, several hundred atoms are trapped and brought into a state that still causes physicists a lot of headaches today.
Controlling the amount of phosphate in cells, the processes involved in catalysts, land use in Madagascar and a paradox of quantum physics – these are the topics for which the Swiss Academy of Sciences (SCNAT) has awarded the Prix Schläfli 2019 to the four most important insights gained by young researchers at Swiss universities. Murielle Delley (Chemistry), Matteo Fadel (Physics), Rebekka Wild (Biology) and Julie Zähringer (Geosciences) receive the prize for the findings arrived at in their dissertations. For the first time, six of the candidates for the Prix Schläfli in Physics were also selected to participate in the Lindau Nobel Laureate Meeting.
I rifiuti radioattivi provenienti dai reattori nucleari possono prendere un tempo molto lungo a decadere. Il Plutonio-239 ha un tempo di dimezzamento – che è il tempo impiegato dalla metà degli atomi considerati a decadere – di non meno di 24’000 anni. Ma questo è niente in confronto al tempo di dimezzamento del gas nobile Xenon-124, come è dimostrato da un gruppo di ricercatori internazionali con collaboratori provenienti dall’Università di Zurigo.
A partire da 2026, le prestazioni dei grandi esperimenti al laboratorio Europeo di fisica delle particelle, il CERN, a Ginevra, saranno aumentate notevolmente.

CERN in Geneva is the leading particle physics laboratory worldwide. Large particle accelerators based on the most innovative technologies are used there for fundamental research. One year ago, the innovation park “PARK INNOVAARE” in Villigen (AG) launched, together with CERN, the BIC of CERN program: it supports start-ups and high-tech micro-companies using CERN technologies for commercial applications. These days the second call for proposals has started.
The Swiss Academies of Arts and Sciences have been requested by the Confederation to prepare roadmaps for research infrastructures for the various scientific fields. These roadmaps will provide a basis for decision-making on the allocation of federal funding for costly research facilities over the period 2025–2028. SCNAT is responsible for implementing this new procedure within the Swiss Academies, and Secretary General Jürg Pfister believes that it offers the scientific community an opportunity for wider involvement.
The LHCb collaboration at CERN has seen, for the first time, the matter–antimatter asymmetry known as CP violation in a so-called D0 meson. LHCb is one of the four large experiments performed at the Large Hadron Collider (LHC) with Swiss participation of Ecole polytechnique fédérale de Lausanne (EPFL) and University of Zurich.
Fünf junge Schweizer haben sich für die Internationale Physik-Olympiade vom 7. bis 15. Juli in Tel Aviv, Israel qualifiziert. Sie gewannen Gold an der 23. Schweizer Physik-Olympiade 2019.
La forza di gravità ci accompagna in ogni momento della nostra giornata – dalla mattina, quando ci alziamo dal letto, fino a tardi la sera quando stanchi morti cadiamo sul materasso. Sebbene nessuna altra forza condizioni le nostre vite tanto quanto la gravità, essa ci rimane quasi sconosciuta. Molti scienziati nel mondo stanno cercando di svelare i segreti della gravità. Uno di questi sta conducendo le sue ricerche nel cantone Argau: la 32enne fisica delle particelle Anna Soter.
The CHIPP Prize is to reward annually the best PhD student in Experimental or Theoretical Particle Physics. In the evaluation, emphasis will be given to the quality of PhD scientific work and to its relevance within the student's research group, as well as to novel ideas brought up by the candidate.
The Periodic Table of Chemical Elements is one of the most significant achievements in science, capturing the essence not only of chemistry, but also of physics and biology. 1869 is considered as the year of formulation of the modern concept of the Periodic System by Dmitri Mendeleev (and others). 2019 is the 150th anniversary of this formulation and has therefore been proclaimed the "International Year of the Periodic Table of Chemical Elements (IYPT2019)" by the United Nations General Assembly and UNESCO.
À une époque où beaucoup de pays d'Europe se refermaient sur eux-mêmes, la Suisse ouvrait une station de recherche à vocation internationale au Jungfraujoch. Plusieurs prix Nobel y ont travaillé. En 2019, la station se voit honorée de deux récompenses qui la consacrent Grand site historique des sciences. La Société européenne de physique lui rend honneur dans le domaine des sciences physiques et l'Académie suisse des sciences naturelles dans celui de la chimie.

In the first workshop in April, the status of the field was reviewed and discussed. The CHIPP input for the discussion of the ESPP update was then agreed during the second workshop held in September. This document describes the CHIPP position on the ESPP update focused on the scientific issues.
APPEC strongly supports and encourages the prospects of an even stronger synergy between Astroparticle Physics and Cosmology with Particle Physics. Areas of synergy between the above domains are identified: dark matter and dark energy; multi-messenger astrophysics, with the recently achieved discoveries of gravitational waves and the extraordinary opportunities also offered by gamma-ray and neutrino observatories for the exploration of powerful accelerators of the universe; the current neutrino precision program in relationship with cosmology, that promise either an unprecedented confirmation of the two standard models of Particle Physics and Cosmology, or a gate to new physics beyond both. These synergies include R&D on photosensors, cryogenic and vacuum techniques, optimisation of large scale infrastructures (civil infrastructure, vacuum, cryogenics) and of their governance and long-term operation, computing strategies for analysis and handling of large volumes of data, and policies leading to open science. Their development also requires grounding fundamental science within society, including, outreach and education. In view of the above synergies the present document introduces and briefly discusses four recommendations related to the role of PP in i) the dark matter searches; ii) the multi-messenger astronomy,in particular the 3G GW experiments (ET); iii) the neutrino physics; iv) the creation of a European Center for AstroParticle Theory (EuCAPT).

Neutrinos are electrically neutral and very light elementary particles, which interact only weakly with other matter and are therefore difficult to observe. From 2025, a new neutrino experiment in the US aims contributing to a better understanding of the neutrinos. At the University of Bern physicists are currently working on the prototype for a detector to be used in the upcoming experiment.
IPPOG, the International Particle Physics Outreach Group, is a collaboration comprising 27 signing member-organizations (countries, laboratories, experiments) whose goal is to maximize the impact of education and outreach efforts related to particle physics.
PiA offers 24 entertaining physics experiments to do yourself again this year. Due to the great interest from abroad, physics will be available in English during Advent, just like last year.
