Physicists are finalizing plans for MATHUSLA, a powerful new addition to CERN’s Large Hadron Collider that will detect long-lived particles and potentially open the door to new physics.

Researchers at the CMS collaboration at CERN have reported the discovery of the smallest hadron in existence, the toponium.

As if atoms weren’t already mind-blowingly small, never mind subatomic particles, CERN researchers in the CMS Collaboration ...

At that time, pure physics research concentrated on understanding the inside of the atom, hence the word "nuclear". Today, our understanding of matter goes much deeper than the nucleus, and CERN's ...

GENEVA (AP) — Top minds at the world's largest atom smasher have released a blueprint for a much bigger successor that ...

But while the LHC has proven a success when it comes to the Higgs, whose existence was confirmed by CERN scientists in 2012, the atom smasher has also been a failure when it comes to new particles.

GENEVA (AP) — Top minds at the world's largest atom smasher have released a blueprint ... on a project roughly a decade in the making at CERN, the European Organization for Nuclear Research.
