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. The mass of the…

  For the first time, the CMS experiment has observed the rare electroweak production of two Z bosons in association with two jets. This achievement completes the observation of all electroweak productions of vector boson pairs (WW, WZ, and ZZ),…

  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. Most matter around us is made…
