CERN Accelerating science

Dr Azadeh Maleknejad, a fellow in the Theoretical Physics department, was awarded second prize for her work on axion physics on 2 February 2022

During the Lepton Photon Conference this week, the ATLAS collaboration presented a new paper that describes how partons interact within the proton

A duo of theorists proposes a new theory to explain both the surprisingly small mass of the Higgs boson and the puzzling symmetry properties of the strong force

The collaboration has made the most precise comparison yet between protons and antiprotons and tested whether or not they behave in the same way under the influence of gravity

A unique combination of high-quality experimental data and several state-of-the-art nuclear-physics models has resulted in an excellent agreement between experiment and theory

The collaboration reports a value for the Higgs boson’s lifetime that has a small enough uncertainty to confirm that the particle has a tiny lifetime

The ALICE collaboration has for the first time observed the residual strong interaction between protons and phi mesons

The unusual nuclear physics phenomenon, first discovered at CERN’s ISOLDE facility 50 years ago, had until now been seen only in mercury isotopes

In a first for particle physics, the CMS collaboration has observed three J/ψ particles emerging from a single collision between two protons
