Upon close inspection, the tetraquark family members are consistent with tightly bound diquark pairs
The CMS Collaboration has identified three extremely rare same-flavor teraquark states and determined, based on their spin-parity configuration,…
The CMS experiment utilises cutting-edge machine learning techniques to search for microscopic, quantum black holes and other exotic objects that evaporate in an instant.
Black holes are amongst the most fascinating objects in the universe.…
Using data collected from 2016 to 2023 and cutting-edge machine learning, CMS observes for the first time the creation of a top quark together with a W and a Z boson – a process so rare it occurs only once in a trillion proton-proton…
In the first search of its kind at a particle collider, the CMS experiment looks for partially visible sprays of particles (jets), containing leptons and dark matter using physics-informed machine learning.
Can we shed light on dark matter?…
CMS scientists are on the hunt for a new, heavy particle that decays into a pair of Higgs bosons. Using the final state with two bottom quarks and two tau leptons, the search sets the most stringent limits to date in the mass range 1.4–4.5…
Turning the LHC into a photon collider, the CMS experiment observes for the first time how two photons fuse and convert into two W bosons. Stringent limits are set on parameters that would describe possible deviations from the standard…
In a first search of its kind at the LHC, the CMS experiment looks for light beyond-the-standard-model particles with a mass in the GeV range that decay into charged hadrons and muons. It establishes that if they exist, they would be produced…
In a much anticipated result, the CMS experiment presents the legacy combination of Higgs boson studies using the full LHC Run 2 data, recorded between 2016 and 2018 – the result is the most precise and comprehensive measurement of the Higgs…
The CMS Collaboration probes decays of the Z boson which would defy our expectations of lepton behavior
How strict are Nature's conservation laws governing the interactions among elementary particles? Physicists once assumed, based on experience…
Measuring the charge asymmetry in W boson-associated production for the first time, paves the way for testing the coupling of the Higgs boson to charm and lighter quarks.
A new angle on Higgs physics
In a new analysis, the CMS experiment at CERN…
An interactive version of the event display is found on a separate, full page here.
For the first time at a hadron collider, the CMS experiment measures the mass of the W boson from hadrons.
Hadrons are particles made out of quarks and gluons, and…
The CMS collaboration expands the search for supersymmetry by exploring a wide variety of final states with boosted particles, in a new analysis called “razor boost”.
Supersymmetry, or SUSY, which suggests that every known particle has a new…
