In the wake of partons
The CMS experiment reports the first observation of a “wake” created by a fast-moving parton in quark-gluon plasma.
-
Looking for new physics at the multiboson frontier
The CMS experiment presents a novel search for new physics by studying collisions that produce three W or Z bosons.
-
Estranged siblings? Observed meson decays are compatible with one bottomonium state, but without any hint of its partner
The CMS experiment reports the observation of a peaking structure in the Υ(1S)ϕ(1020) channel in proton-proton collisions at 13 TeV.

In search of new particles like the Higgs boson
Could there be more particles like the Higgs boson?
-
The curious case of quarkonia inside jets
The CMS experiment presents a first study of the ϒ mesons (bound states of a bottom quark and antiquark) produced within jets.
-
What’s inside quarks? CMS looks deeper
CMS probes the inside of quarks down to distances of 10–20 m – smaller than ever before – searching for potential more fundamental building blocks within them.
-
Testing the heaviest quark’s interaction with light
The CMS Collaboration has completed the most precise measurement to date of top-quark production in association with a photon Using the full Run 2 dataset of the LHC and advanced machine learning techniques, the CMS Collaboration has delivered the most precise measurement to date of top quark production in association with a photon.
-
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.
-
CMS observes rare Z boson pair production
For the first time, the CMS experiment has observed the rare electroweak production of two Z bosons in association with two jets.
-
CMS observes another indication of a momentary union of the heaviest quarks, now in the lepton + jets final state
The CMS experiment provides the first confirmation of the excess observed in top quark-antiquark production that is consistent with the short-lived bound state – toponium – decaying to a lepton + jets final state.
