Limits on the Higgs boson lifetime and width from its decay to four charged leptons

Constraints on the lifetime and width of the Higgs boson are obtained from H arrow right ZZ arrow right 4[scriptl] 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.

Zusammenfassung:	Constraints on the lifetime and width of the Higgs boson are obtained from H arrow right ZZ arrow right 4[scriptl] 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]H3.5x10-9 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 [lower right quadrant]H
