CMS observes rare collisions that produce pairs of electrons or muons with the highest combined invariant mass ever recorded, extending the search for undiscovered heavy particles.
The CMS experiment reports the observation of a peaking structure in the Υ(1S)ϕ(1020) channel in proton-proton collisions at 13 TeV.
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.
The CMS experiment reports the first observation of the rare decay of an eta meson to two muons and two electrons.
CMS sets the world’s most stringent limits on B⁰ and B⁰ₛ decays into four muons.
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.
CMS pushes the sensitivity frontier towards a measurement of the rare Higgs boson decay into a Z boson and a photon
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.
