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.

Hunting the heavy Z: Searching for a new Z boson by studying hadronic decays of top quark pairs
The CMS experiment has conducted a search for heavy beyond-standard-model particles (referred to as a Z′ boson) that give rise to a top quark-antiquark pair decaying into hadrons.

Unveiling B Meson Production at CMS
The ratios of the B meson production fractions have been measured for the first time in the CMS experiment.
-
Peeking inside the proton: the story of Z+ϒ
CMS discovers associated production of a Z boson and an ϒ meson.
-
The Higgs boson with toppings
The Higgs boson is deeply connected to the mechanism that generates the masses of elementary particles.
-
The “Large Photon Collider”: CMS observes scattering of light by light at the LHC
CMS scientists discover some of the rarest collisions that the LHC can produce – such as the scattering of light by light – and learn more about the quantum nature of electromagnetism, search for new particles, and much more.
-
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.

A charming look into the structure of nuclei using collisions with photon clouds
In a recent result, the CMS experiment measures the production of charmed D0 mesons in collisions of a photon with a heavy lead nucleus for the first time.
