CERN Accelerating science

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

The Higgs boson holds the record (48 years) among elementary particles for the time between prediction and discovery, going from an esoteric technicality to commanding the global spotlight at the world’s most powerful collider

Beams of protons are again circulating around the collider’s 27-kilometre ring, marking the end of a multiple-year hiatus for upgrade work

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

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

On 3 March 2022, CERN Director-General Fabiola Gianotti and Brazilian Minister for Science, Technology and Innovation Marcos Pontes signed an agreement admitting Brazil as an Associate Member State of CERN

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

The finding may help determine whether or not any antimatter seen by experiments in space originates from dark matter

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

Pursuing CERN’s scientific mission through environmentally responsible research

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