Chasing light-weight particles in Higgs boson decays using pairs of electrons
The CMS experiment sets limits for BSM particles down to tens-of-MeV aided by machine learning techniques.

The Higgs boson as a window into dark matter
The CMS experiment studies the Higgs boson as a potential window into dark matter, and sets constraints on this mechanism, which gives rise to isotropic sprays of low-energy particles.

Hidden signals of new physics in events with a high energy lepton pair
A primary goal of the Large Hadron Collider (LHC) is to hunt for evidence of beyond the Standard Model (BSM) dynamics through deviations from the Standard Model (SM) predictions.

Testing universality – particle equality at stake
In the world of elementary particles, there are twelve generic types of fermions (spin ½ particles): 3 up-type quarks, 3 down-type quarks, 3 charged leptons, and 3 neutrinos.

Exploring the dark sector: looking for the most hidden light dark matter
The completion of the standard model (SM) with the discovery of the Higgs boson stands as a resounding success in the world of particle physics.

Peek into the hidden sector using long-lived particles in Run 3
The discovery of the Higgs boson represents a significant breakthrough in understanding the universe’s fundamental structure and dynamics.

Same LHC, same CMS, more physics
A new CMS paper describes how the CMS experiment can squeeze more physics out of the LHC data by using smarter data selection/reduction techniques.
