Proton-Proton Collision (LHC, CERN)

Modern physics relies on an elegant «Standard Model of particle physics», a quantum field theory based on three symmetries and a symmetry breaking. This theory describes and explains magnificently all experimental results obtained so far. With the discovery of the Higgs particle in 2012 at the Large Hadron Collider at CERN, the last missing piece of the Standard Model has been experimentally confirmed. Experiments at CERN and at other international laboratories now continue to test the validity and limits of the Standard Model in ever widening scope. However, for a comprehensive understanding of the laws of nature a theory beyond the Standard Model is needed, which should include gravitation and explain the presence of dark matter and dark energy in the universe.

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:

Comparison between RK measurements. The measurements by the BaBar and Belle collaborations combine B+→K+ℓ+ℓ− and B0→KS0ℓ+ℓ− decays, where ℓ is a lepton. The previous LHCb measurements and the new result [4], which supersedes them, are also shown.
