CERN Accelerating science

New ATLAS measurement of lepton flavour universality, a key feature of the Standard Model, in decays of the W boson is more precise than all previous measurements combined

The result has implications for future searches for rare beauty meson decays and for the interpretation of results from the Fermilab g-2 experiment

Peter Higgs passed away on 8 April at the age of 94

The interaction strength of neutrinos had never previously been measured in this energy range

The CERN facility allowed scientists to see how this rare Earth metal is synthesised in stars. The results open up new questions about stellar nucleosynthesis and the chemical evolution of galaxies

With this measurement the LHC is again demonstrating its ability to provide very high-precision measurements and bringing new insights into an old mystery

Using the outstanding tracking capabilities of the CMS detector, the collaboration observed two photons producing two tau-leptons in proton–proton collisions

This search uses computer vision techniques to look for collimated bursts of light, a potential signature of Higgs partner particles

The CMS collaboration has measured the speed of sound in the quark–gluon plasma more precisely than ever before, offering new insights into this extremely hot state of matter

In cooling positronium with laser light for the first time, AEgIS may also have taken the first step towards a matter–antimatter system that emits laser-like gamma-ray light
