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.
It takes two: CMS observes signs of attraction between top quark pairs
An excess in data hints at the existence of a top quark-antiquark quasi-bound state, called “toponium”.
The flavour of new physics
The CMS Collaboration investigates whether physics plays favorites with quarks.
Piecing together the puzzle: a comprehensive look at vector boson scattering
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.
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.
