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

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.

One-loop electroweak factorizable corrections for the Higgsstrahlung at a linear collider

We present standard model predictions for a four fermion reaction e+ e- -> mu+ mu- bar_b b being one of the best detection channels of a low mass Higgs boson produced through the Higgsstrahlung mechanism at a linear collider. We include leading virtual and real QED corrections to all the lowest order Feynman diagrams of e+ e- -> mu+ mu- bar_b b and the complete O(alpha) electroweak corrections to the Z-Higgs production and to the Z and Higgs boson decay widths in the double pole approximation.
