On Sunday, May 31, CMS participated in the 5th edition of the Color Run in Cessy, France. This annual event is organized by the town of Cessy for the benefit of local associations supporting people with disabilities.
The seventh CMS Open Data Workshop brought educators to Notre Dame to build teaching materials from real LHC data.
CMS sets the world’s most stringent constraints on anomalous interactions between the bosons that carry the electroweak force.
The CMS experiment uses data collected between 2016 and 2026 to observe, for the first time, leptons (electrons and muons) emitted from protons scattering off one another.
A new boosted jet technique, powered by machine learning, gives CMS its most sensitive search for Higgs bosons breaking apart into never-before-seen particles.
CMS has made the first search in the two-photon and two-bottom-quark final state for a heavy particle with masses from one to four trillion electronvolts.
CMS advances the study of Higgs boson’s self-interaction by searching for Higgs boson pairs decaying into bottom quark–antiquark and tau lepton–antilepton pairs in collisions recorded between 2022 and 2024.
CMS probes the highest-energy lepton pairs ever recorded to search for hints pointing to a Higgs boson made of smaller constituents.
A special test run, with more than twice as many near-simultaneous collisions as usual, allowed CMS to test new methods of tracking and identifying particles, years before the upgraded High-Luminosity LHC comes online.
Using Z bosons, the CMS experiment reveals new details of how the Quark-Gluon Plasma drains energy from energetic quarks and challenges current theoretical descriptions.
