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…
The ATLAS and CMS Experiments at CERN have just released a new measurement of the mass of the top quark. The new result combines 15 previous measurements to give the most precise determination of the top-quark mass to date.
Among the known…
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. This is the most precise measurement of the Higgs boson mass achieved by a…
