Abstract

Constraints are presented on the total width of the recently discovered Higgs boson, H , using its relative on-shell and off-shell production and decay rates to a pair of Z bosons, where one Z boson decays to an electron or muon pair, and the other to an electron, muon, or neutrino pair. The analysis is based on the data collected by the CMS experiment at the LHC in 2011 and 2012, corresponding to integrated luminosities of 5.1 fb -1 at a center-of-mass energy s = 7 TeV and 19.7 fb -1 at s = 8 TeV.
