For the first time ever, the CMS experiment has designed a dedicated analysis using parametrised machine learning to look for new dark particles that don’t socialize with Standard Model fermions, one of them being a favourite candidate in the…

CMS sees evidence of the Upsilon meson decaying into two tau leptons for the first time at a hadron collider Beyond our best current understanding of particle physics, encapsulated in the standard model, various theoretical models predict the…
