Abstract

The potential of measurement of the relative statistical uncertainty of the σ(HZ)× BR(H → WW*) decay, at the International Linear Collider (ILC) has been presented. The study is performed at the lowest energy stage of the proposed staged ILC, the 250 GeV stage. Monte Carlo samples representing all SM processes were passed through full detector simulation of the International Large Detector (ILD) model. Fully hadronic final state has been analyzed using an integrated luminosity of 500 fb-1, using multivariate analysis technique. The obtained relative statistical uncertainty Δ(σ⋅ BR) / (σ⋅ BR) of the σ(HZ)⋅ BR(H→ WW^*) is 4.1%.
