Abstract
In this paper we present results of the determination of the statistical precision of the branching
fraction measurement, for Higgs decaying to 𝑍 𝑍∗ pairs at 3 TeV and 350 GeV CLIC. Measurements
are simulated with the CLIC_ILD detector model, taking into consideration all relevant physics
and beam-induced background processes. It is shown that the product of the branching fraction
𝐵𝑅(𝐻 → 𝑍𝑍∗) and the Higgs production cross-section can be measured with a relative statistical
uncertainty of 3% (20%) at 3 TeV (350 GeV) center-of-mass energy, using semileptonic final states
and assuming an integrated luminosity of 5 (1) ab−1.
