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.
An excess in data hints at the existence of a top quark-antiquark quasi-bound state, called “toponium”.
The CMS Collaboration investigates whether physics plays favorites with quarks.
The CMS experiment performs a combined measurement of the scattering of W and Z bosons in the several possible final states, improving over the precision of each individual result.
The CMS experiment conducts the first search for dark matter particles produced in association with an energetic narrow jet—the pencil jet.
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.
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 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.
The ratios of the B meson production fractions have been measured for the first time in the CMS experiment.
