Limits on the Higgs boson lifetime and width from its decay to four charged leptons
Original language description
Constraints on the lifetime and width of the Higgs boson are obtained from H -> ZZ -> 4l events using data recorded by the CMS experiment during the LHC run 1 with an integrated luminosity of 5.1 and 19.7 fb(-1) at a center-of-mass energy of 7 and 8 TeV,respectively. The measurement of the Higgs boson lifetime is derived from its flight distance in the CMS detector with an upper bound of tau(H) < 1.9 x 10(-13) s at the 95% confidence level (C.L.), corresponding to a lower bound on the width of Gamma(H)> 3.5 x 10(-9) MeV. The measurement of the width is obtained from an off-shell production technique, generalized to include anomalous couplings of the Higgs boson to two electroweak bosons. From this measurement, a joint constraint is set on the Higgs boson width and a parameter f(Lambda Q) that expresses an anomalous coupling contribution as an on-shell cross-section fraction. The limit on the Higgs boson width is Gamma(H) < 46 MeV with f(Lambda Q) unconstrained and Gamma(H) < 26 MeV f
