The CMS experiment reports the observation of a peaking structure in the Υ(1S)ϕ(1020) channel in proton-proton collisions at 13 TeV. Using the Run 2 proton-proton collision dataset collected at the LHC between 2016 and 2018, the CMS Collaboration ha…

  The CMS Collaboration announces several new results for LHCP 2026. Among the highlights are four new results including 2025 data, and two comprehensive performance papers. CMS presents a competitive measurement of time-dependent CP violation i…

  The CMS experiment reports the first observation of the rare decay of an eta meson to two muons and two electrons. The CMS detector was originally built to discover the Higgs boson and search for heavy particles that could transform our unders…
