Comparison of Higgs Boson Mass and Width Determination of the LHC and a Linear Collider
V. Drollinger, A. Sopczak
Abstract
Two important properties of a Higgs boson are its mass and width. They may distinguish the Standard Model (SM) Higgs boson from Higgs bosons of extended models. We show results from a direct mass and width reconstruction for a Higgs boson mass range from 120 to 340 GeV. The mass and width have been reconstructed from the H --> ZZstar --> mu+mu-mu+mu- reaction in an LHC simulation of the CMS detector. The determined mass accuracy has been compared with that obtained from studies for a linear collider (LC). The mass precision from the latter studies is derived by scaling previous LC simulation results according to the expected event rates. For the Higgs boson width we compare a direct determination with indirect methods and find good complementarity.
