Abstract

We have investigated the potential of Higgs boson production at e gamma mode of the Compact Linear Collider (CLIC) to probe anomalous ZZH couplings. Considering two different center of mass energies of CLIC (root s = 1.5 and 3 TeV) and various integrated luminosities, we have calculated 95% confidence level (CL) bounds on the anomalous ZZH coupling parameters Delta a(Z), b(Z) and (b) over tilde (Z). We perform an analysis through the process gamma e -> eZH with systematic uncertainties of delta(sys) = 0%, 5%, 10%. Obtained results have been discussed in terms of capability to probe anomalous ZZH couplings in the photoproduction process.yy
