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…

  The CMS experiment uses data collected between 2022 and 2024 to perform a detailed study of Higgs boson production rates as a function of several variables. The measurements focus on the “golden channel”, characterized by four leptons (electro…

  CMS probes the inside of quarks down to distances of 10–20 m – smaller than ever before – searching for potential more fundamental building blocks within them. In our current understanding of nature, visible matter is made of quarks. Quarks ar…
