The Higgs boson’s shadowy cousin: a CMS search for the dark Higgs
Remember the media buzz when we finally pinned down the Higgs boson in 2012?
-
Top quarks take the t-channel express at 5.02 TeV
For the first time, the CMS experiment measures the production of single top quarks in a mode called the “t-channel” at 5.02 TeV, reporting results aligned with the standard model expectations.
-
CMS has sharpened its eyesight for highly collimated electron-positron pairs
The CMS collaboration has developed a new technique to distinguish electron-positron pairs travelling so closely together that we see them as a single cluster of deposited energy.
-
Beyond the script: Does the Higgs boson improvise in its interactions?
By observing decays of Higgs bosons into pairs of photons, the CMS experiment probes anomalous interactions, including those between Higgs bosons and W/Z bosons or gluons when all particles are replaced with their antiparticles and space is reflected.
-
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.
