Forty years ago today, physicists at CERN announced to the world that they had discovered the electrically charged carrier of the weak force, one of nature’s four fundamental forces

The CAPP axion haloscope at the CAST experiment has hunted for axions from the Milky Way’s “halo” of dark matter, and has narrowed down the theoretical space in which to look for these hypothetical particles

The ATLAS and CMS collaborations have searched for matter–antimatter asymmetry in the interaction between the Higgs boson and the tau lepton

The collaboration has put the seesaw model of neutrino mass to a new test

New ATLAS and CMS analyses place tight limits on the strength of the Higgs boson's interaction with the charm quark

The new detector, known as MAPP, will increase the physics reach of the MoEDAL experiment and the Large Hadron Collider

The collaborations have set stringent new bounds on the fraction of Higgs bosons transforming into invisible particles

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

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 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
