L’objectif de cette réunion est de dresser l’état des connaissances actuelles avec des spécialistes intéressés de l’administration, des associations et d’autres organisations en passant par les émissions, la propagation jusqu’aux effets induits.
Immagine: PixabayIn 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.

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.

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.

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.

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).

Laetitia Laub was born and raised near Lausanne. She studied mathematics and physics at the Federal Institute of Technology in Lausanne (EPFL). Since August 2017, the 24-year-old junior scientist is writing her doctoral thesis in theoretical physics at the University of Bern. In her thesis she deals with the anomalous magnetic dipole moment of the muon and the reaction of this particle in the magnetic field. "Many people are currently working on this theoretical problem with the aim of further reducing the calculation error of the dipol moment. This is also because a better experimental value for the dipole moment will be probably found at Fermilab in the US and J-Parc experiment in Japan soon, " says Laetitia Laub.
The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Physics 2018 with one half to Arthur Ashkin (USA) and the other half jointly to Gérard Mourou (France) and Donna Strickland (Canada). Ashkin invented optical tweezers that grab particles, atoms, viruses and other living cells with their laser beam fingers. Mourou and Strickland paved the way towards the shortest and most intense laser pulses ever created by mankind.
At the end of August, climate change and the future energy supply of Switzerland were among the topics of several keynote speeches at the Annual Meeting of the Swiss Physical Society (SPS) and the Swiss Institute of Particle Physics (CHIPP) in Lausanne. Maurice Bourquin, former professor of physics at University of Geneva, gave a keynote lecture about the ongoing transformation of the Swiss energy system. Professor Bourquin was also Rector of the University of Geneva (1999 - 2003) and President of the CERN Council (2001 - 2003). The 77 year-old scientist’s speech was titled: “Thorium-based systems – A new direction for nuclear waste elimination and energy production.” In the interview that follows, Professor Bourquin explains why he still believes in nuclear power.
In order for physicists at CERN to carry out their experiments for the understanding of matter, the large particle accelerator LHC must be operated with the utmost precision. Ensuring this precision both now and in the future was the overriding goal of a doctoral thesis that Claudia Tambasco recently completed at the EPFL in Lausanne. For this work, the young researcher was today (28.08.2018) awarded the prize of the Swiss Institute of Particle Physics (CHIPP) at a ceremony in Lausanne.
Geneva, 28 August. Six years after its discovery, the Higgs boson has at last been observed decaying to fundamental particles known as bottom quarks. The finding, presented today at CERN by the ATLAS and CMS collaborations at the Large Hadron Collider (LHC), is consistent with the hypothesis that the all-pervading quantum field behind the Higgs boson also gives mass to the bottom quark. Both teams have submitted their results for publication today.

In 2021, the European research satellite Euclid will be launched into space. With Euclid, scientists from Switzerland and 15 other countries want to gain a better understanding of dark matter and dark energy. These two 'things' fill large parts of the universe in the view of modern astronomy, but neither dark matter nor dark energy have been directly observed so far. Researchers at the University of Zurich have prepared a complex computer simulation of dark matter in preparation for the Euclid mission. This mission is of great interest not only to astronomers and astrophysicists but also to particle physicists since particle physics is on the quest for the discovery of the nature and structure of dark matter with its own experiments.
If you are looking for unknown things, you usually do not know which way to go to find the unknown. This dilemma is also faced by scientists who want to advance into previously unknown areas of elementary particle physics. And yet they have to find a consensus on which experiments promise the greatest gain in knowledge in the next years and decades. For this purpose, the Swiss particle physicists are currently working on a new research roadmap.
These days, the Swiss-Italian documentary 'CERN and the sense of beauty' will be screened in selected Swiss cinemas. The work of the Italian director Valerio Jalongo combines images from the particle physics research laboratory with nature photographs and with works of art, leading to a subjective and idiosyncratic meditation on knowledge and beauty.
The large particle accelerator LHC at CERN in Geneva enables scientists to get precious clues to understand the nature of matter in the next two decades of data taking. The power and performance of this huge research apparatus needs to be constantly improved for this task. A silicon sensor, which the junior researcher Claudia Merlassino is currently testing at the University of Bern, is planned to be used from 2025 in a large LHC experiment: ATLAS.
CERN in Geneva is the world's largest facility for the study of fundamental particles. The equipment that usually serves science can sometimes be used for practical purposes too. That's for example the case for the protons emerging from the Proton Synchrotron Booster (PSB): they are used in the large particle accelerator LHC for scientific experiments. The protons can also be used to produce isotopes that are useful in radiation medicine. Such isotopes are produced in the recently opened facility CERN-MEDICIS.
