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.

Teaching machines to see the invisible: the DeepMET algorithm
The CMS experiment employs a new machine-learning algorithm to improve the reconstruction of invisible particles.
-
B* mesons are excited to (finally) show up
For the first time ever, the excited states of three beauty mesons are fully reconstructed and their masses are measured directly, using data from the CMS experiment.

Search for boosted Higgs advances our understanding of dark matter
The CMS Collaboration hunts for Higgs bosons recoiling against dark matter particles Dark matter is one of the most perplexing mysteries of our universe, accounting for roughly 27% of its total energy.

Quarks running for freedom: Probing the strong force at high precision
The CMS experiment achieves the most precise determination of the strength of the strong nuclear force using the rates of production of jets at several centre-of-mass energies.

Beyond light: Probing dark matter and extra dimensions with CMS
By studying events with only a single energetic photon, the CMS experiment places some of the most stringent constraints to date on dark matter models and theories predicting extra dimensions of space.

Looking for early vacuum-like emissions in jets in heavy ion collisions
CMS explores the early stages of jet evolution in heavy-ion collisions When heavy ions such as lead (Pb) collide in the LHC, a new state of matter called the quark-gluon plasma (QGP) is formed.
-
Probing interactions among trios of heavy vector bosons at record energy
CMS presents the most precise measurement of WWZ production to date by combining Run 2 data with more recent Run 3 data.
-
Topping up the charming Higgs
The CMS experiment presents the first-ever search for a Higgs boson decaying to charm quarks when the Higgs boson is produced along with two top quarks.
-
Broken mirrors: Do top quarks and Z bosons defy charge-inversion and reflection symmetry?
For the first time, the CMS experiment has employed physics-informed machine learning to observe whether the laws of physics still hold true when top quarks and Z bosons are replaced with their antiparticles and space is reflected.
