Measurements of properties of the Higgs boson decaying into the four-lepton final state in pp collisions at √s=13 TeV

Properties of the Higgs boson are measured in the H → ZZ → 4` (` = e, µ) decay channel. A data sample of proton-proton collisions at √ s = 13 TeV, collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 35.9 fb−1 is used. The signal strength modifier µ, defin...
