Higgs Boson production in e+e− → μ+μ−bb

The production of the Standard Model Higgs boson in the four-fermion reaction e+e− → μ+μsu−bb is studied. The complete tree-level matrix element, including signal and backgrounds in the standard electroweak theory, is computed and initial state radiation is taken into account in the leading-log approximation. A Monte Carlo event generator has been built, and numerical results for some distributions of experimental interest in the search for the Higgs particle at future electron-positron colliders are shown, compared with those existing in the literature and commented.
