A tale of two Higgs: The quest for production of Higgs boson pairs at CMS
In a recent result, the CMS experiment has combined a comprehensive set of searches for the production of not one but two Higgs bosons – the result is a significant step towards observation of this elusive process, and constitutes a legacy of the Run 2 data taking era at the LHC.

Clocking nature’s heaviest elementary particle: Do top quarks play by Einstein’s rules the whole day and night?
In a first measurement of its kind at the LHC, the CMS experiment tests whether top quarks adhere to Einstein’s special theory of relativity, and improves the bounds on noncompliance by up to a factor of one hundred with respect to previous results.

Rediscovering the Higgs boson at 13.6 TeV
Going back to the origins, in a latest result, the CMS experiment rediscovers the Higgs boson and measures its rate of production in the “golden channel”, now at the unprecedented centre-of-mass energy of 13.6 TeV.

CMS at Higgs Hunting, Hard Probes, TOP 2024
The CMS Collaboration has announced 14 new results for summer topical conferences – Higgs Hunting 2024, Hard Probes 2024, and TOP 2024. In HIG-22-013, we present a search for a heavy scalar or pseudoscalar boson decaying to a top quark-antiquark pair.

CMS delivers the best-precision measurement of the W boson mass at the LHC
In an extraordinary feat of precision physics, CMS measures the mass of the W boson, and finds it to be in good agreement with the prediction by the Standard Model of particle physics.

Hidden signals of new physics in events with a high energy lepton pair
A primary goal of the Large Hadron Collider (LHC) is to hunt for evidence of beyond the Standard Model (BSM) dynamics through deviations from the Standard Model (SM) predictions.

Artificial neural networks in search for excited tops
With the discovery of the Higgs boson in 2012, an important piece in our puzzle to understand the Universe was found.

Exploring new frontiers: Searching for a heavy Higgs boson decaying to four leptons
The Higgs boson is a fascinating elementary particle, and its discovery twelve years ago cemented the standard model (SM) of particle physics as the most accurate description of nature at and below the electroweak energy scale.

Journey through the Quark Gluon Plasma
At the LHC, lead ions are smashed together at extremely high speeds to create a unique state of matter called the quark gluon plasma.
