Dark matter and pencil jets: The search for a low-mass Z' boson using machine learning
The CMS experiment conducts the first search for dark matter particles produced in association with an energetic narrow jet—the pencil jet.
Mind the gap! Top quark pairs with W bosons continue to defy the latest predictions
In a recent measurement, the CMS experiment confirms a slight but persistent disagreement between the simulated and the observed rates of events in which a top quark pair is produced accompanied by a W boson.
Shiny top quarks: what happens when top quarks emit light?
The CMS experiment has conducted a comprehensive study of the rates of production of top quark pairs created along with a photon, both inclusively and as a function of several kinematic variables.
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.
Unveiling B Meson Production at CMS
The ratios of the B meson production fractions have been measured for the first time in the CMS experiment.
