Abstract: 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 tH<1.9×10-13??s at the 95% confidence level (C.L.), corresponding to a lower bound on the width of GH>3.5×10-9??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?Q that expresses an anomalous coupling contribution as an on-shell cross-section fraction. The limit on the Higgs boson width is GH<46??MeV with f?Q unconstrained and GH<26??MeV for f?Q=0 at the 95% C.L. The constraint f?Q<3.8×10-3 at the 95% C.L. is obtained for the expected standard model Higgs boson width.
