Measurement of the H to ZZ branching fraction at a 350 GeV and 3 TeV CLIC

Le résumé fourni par la source

In this paper we investigate the prospects for measuring the branching fraction of the Standard Model Higgs boson decay into a pair of $Z$ bosons at the future Compact Linear Collider (CLIC) at 350 GeV and 3 TeV center-of-mass energies. Studies are performed using a detailed simulation of the detector for CLIC, taking into consideration all relevant physics and beam-induced background processes. It is shown that the product of the Higgs production cross section and the branching fraction $\mathrm{BR}(H\ensuremath{\rightarrow}Z{Z}^{*})$ can be measured with a relative statistical uncertainty of 20% (3.0%) at a center-of-mass energy of 350 GeV (3 TeV) using semileptonic final states, assuming an integrated luminosity of $1\text{ }\text{ }{\mathrm{ab}}^{\ensuremath{-}1}$ ($5\text{ }\text{ }{\mathrm{ab}}^{\ensuremath{-}1}$).
