The CMS experiment announces new results for the EPS-HEP conference 2025 in Marseille. The new results comprise searches for new phenomena using exotic signatures to precision measurements of standard model processes. Links to the Physics Anal…

This year, the LHC is colliding more than protons and lead ions: oxygen and neon have also made it into the collider, and are being studied by CMS and the other LHC experiments in order to understand the early universe! This is the first time that ox…

The CMS experiment sets limits for BSM particles down to tens-of-MeV aided by machine learning techniques. Axion-like particles (ALPs) are hypothetical light-weight neutral bosons that could solve deep mysteries in physics, from the strong CP proble…
