Effects of polarisation on study of anomalous VVH interactions at a Linear Collider

Abstract

We investigate the use of beam polarisation as well as final state $\tau$ polarisation effects in probing the interaction of the Higgs boson with a pair of heavy vector bosons in the process $e^{+}{e}^{-}\to f\bar{f}H$, where $f$ is any light fermion. The sensitivity of the International Linear Collider (ILC) operating at $\sqrt{s}=500$ GeV, to such $VVH$($V=W/Z$) couplings is examined in a model independent way. The effects of ISR and beamstrahlung are discussed.
