Could there be more particles like the Higgs boson? For the first time, the CMS experiment has searched for the decay of the Higgs boson into two more Higgs-boson-like particles with unequal masses. Some theories suggest that the Higgs boson m…

CMS pushes the sensitivity frontier towards a measurement of the rare Higgs boson decay into a Z boson and a photon The 2012 discovery of the Higgs boson at CERN by CMS and ATLAS was a landmark achievement in the world of particle physics - but it w…

  The CMS experiment presents a first study of the ϒ mesons (bound states of a bottom quark and antiquark) produced within jets. The results reveal significant discrepancies between the observed data and current theoretical predictions, offering…
