The collaboration has observed a new kind of “pentaquark” and the first-ever pair of “tetraquarks”

The CMS experiment awaits LHC Run 3 to explore several analyses showing small disagreements with theory expectations

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

Precise knowledge of the top-quark mass is of paramount importance to understand our world at the smallest scale

The collaboration has tackled challenging supersymmetry scenarios, surpassing long-standing limits set by the LEP collider

A new analysis by the ALICE collaboration confirms the expected role of quark mass in the interactions of quarks with a quark–gluon plasma

With its high statistical significance, the result represents the first observation of electroweak top-quark–photon production

Physicists at the ATLAS experiment are on the hunt for new, long-lived particles to help explain several outstanding mysteries of our Universe
