Factorizable corrections to e+e- -> mu+ mu- b bar_b at a linear collider

Abstract

We discuss the standard model factorizable radiative corrections to e+e- -> mu+ mu- b bar_b, which is one of the best detection channels of the low mass Higgs boson produced through the Higgsstrahlung mechanism at a linear collider. The discussion includes the leading virtual and real quantum electrodynamics corrections due to the initial state radiation, the one-loop electroweak factorizable corrections to the on-shell Higgsstrahlung reaction and to subsequent decays of the Z and Higgs boson, and the quantum chromodynamics corrections to the Higgs boson decay width into a b bar_b-quark pair.
