Chasing dark matter with mysterious electron pairs
The CMS experiment performs the first collider search for “inelastic dark matter” in the case where dark-matter particles travel a measurable distance before decaying into a pair of low-momentum electrons.

Is the Higgs boson truly elementary?
CMS probes the highest-energy lepton pairs ever recorded to search for hints pointing to a Higgs boson made of smaller constituents.
-
Hunting heavy particles through high-mass pairs of electrons or muons
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.

What’s inside quarks? CMS looks deeper
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.
-
Unlocking the vault of new physics
In Run 3, CMS expanded its trigger program to enhance capturing long-lived particles that decay far away from the point of collision – broadening the search for physics beyond the Standard Model.
-
Are there quantum black holes that evaporate instantly?
The CMS experiment utilises cutting-edge machine learning techniques to search for microscopic, quantum black holes and other exotic objects that evaporate in an instant.

Using physics-based machine learning to hunt dark matter
In the first search of its kind at a particle collider, the CMS experiment looks for partially visible sprays of particles (jets), containing leptons and dark matter using physics-informed machine learning.

How CMS records all 40 million events per second
The CMS experiment is utilising a novel technique called L1 Scouting, which allows it to record data from all collisions, without any selection, but in a reduced format.

Hunting exotic Higgs bosons decaying to lightweight scalar particles
In a first search of its kind at the LHC, the CMS experiment looks for light beyond-the-standard-model particles with a mass in the GeV range that decay into charged hadrons and muons.

One photon short: Recovering lost photons using AI to hunt for exotic Higgs boson decays
CMS breaks new ground by reconstructing challenging photon signatures using machine learning, opening new paths in the search for physics beyond the standard model.
