Radiative corrections to single Higgs boson production in e+e− annihilation

For energies relevant to future linear colliders, s≳500 GeV, the WW fusion channel dominates the Higgs boson production cross section e+e−→ν̄νh0. We have calculated the one-loop corrections to this process due to fermion and sfermion loops in the context of the MSSM. As a special case, the contribution of the fermion loops in the SM has also been studied. In general, the correction is negative and sizeable of the order of 10%, the bulk of it being due to fermion loops.
