How much does the Higgs boson weigh? CMS gives its most precise answer yet
Combining measurements from two Higgs boson decay channels, the CMS experiment determines the particle’s mass to be 125.065 GeV, with an uncertainty of just 88 MeV.

Two Higgs or not two Higgs? CMS advances the search for Higgs boson pair production
CMS advances the study of Higgs boson’s self-interaction by searching for Higgs boson pairs decaying into bottom quark–antiquark and tau lepton–antilepton pairs in collisions recorded between 2022 and 2024. Is the Standard Model (SM) the ultimate theory of particle physics?

Out of the loop: CMS advances in the search for a rare Higgs boson decay
CMS pushes the sensitivity frontier towards a measurement of the rare Higgs boson decay into a Z boson and a photon The 2012 discovery of the Higgs boson at CERN by CMS and ATLAS was a landmark achievement in the world of particle physics – but it was only the beginning.

From discovery to deep dive: The Higgs boson under the microscope
The CMS experiment uses data collected between 2022 and 2024 to perform a detailed study of Higgs boson production rates as a function of several variables.
-
CMS weighs the Higgs boson using flashes of light
The CMS experiment reports a new measurement of the Higgs boson mass in the decay into two photons, improving the precision of this result over earlier measurements by refining detector calibration and new analysis techniques.

Does the Higgs look a little odd lately?
The CMS experiment has performed a new search for Charge-Parity violation in Higgs boson decays to tau leptons, shedding light on the origin of matter.
-
The tangled dance of Higgs boson decays
For the first time, the CMS experiment probes quantum entanglement in Higgs boson decays to a pair of Z bosons.

From pieces to precision: building the Higgs boson’s clearest portrait to date
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 boson by CMS to date.

CMS measures WH charge asymmetry — a novel probe of the Higgs–charm interaction
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.

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.
