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.
Since the first high-energy proton colliders began operating more than…
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.
Some theories predict that new light particles associated with the Higgs boson…
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.
In a first of its kind, CMS has carried out a search for a heavy particle, X, with masses…
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.
Is the Standard Model (SM) the…
CMS probes the highest-energy lepton pairs ever recorded to search for hints pointing to a Higgs boson made of smaller constituents.
Is the Higgs boson truly an elementary particle, or could it be composed of more fundamental constituents? This…
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.
For a few days during…
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.
To understand the Quark-Gluon Plasma (QGP), the hottest matter in the Universe…
The CMS Collaboration announces 28 new results for ICHEP 2026.
Among the highlights are three new results including 2026 data, and several brand new searches.
The CMS Collaboration is presenting a broad portfolio of new physics results at the…
CMS sets the world’s most stringent constraints on anomalous interactions between the bosons that carry the electroweak force.
A key prediction of the Standard Model of particle physics is how the carriers of the weak force – the W and Z…
