Abstract

We evaluate the expected measurement accuracy of the branching ratio of the StandardModel Higgs boson decaying into tau lepton pairs at the ILC with a full simulation of the ILD detector concept. We assume a Higgs mass of 125 GeV, a branching ratio of BR(h → φ+ φ-) = 6.32 %, a beam polarization of electron (positron) of -0.8(+0.3), and an integrated luminosity of 250 fb-1. The Higgs-strahlung process e+e- → Zh with Z → qq is analyzed. We estimate the measurement accuracy of the branching ratio δ( δ × BR)/( δ × BR) to be 3.4% with using a multivariate analysis technique.
