Among the leading candidates to describe physics beyond the standard model of particle physics is Supersymmetry, a new symmetry that posits the existence of a partner particle for each known particle in the standard model. Supersymmetry, or “SUSY”…
The data reveal that the particle discovered at CERN continues to behave just like the Standard Model predicts
Since the discovery of a Higgs boson by the CMS and ATLAS Collaborations in 2012, physicists at the LHC have been making intense efforts…
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…
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.
