摘要：

We present the first complete calculation of the one-loop electroweak effect in the process of semi-inclusive bottom-Higgs production at LHC in the minimal supersymmetric standard model. The size of the electroweak contribution depends on the choice of the final produced neutral Higgs boson and can be relevant, in some range of the input parameters. A comparison of the one-loop results obtained in two different renormalization schemes is also performed, showing a very good next-to-leading order scheme independence. We further comment on two possible, simpler, approximations of the full next-to-leading order result, and on their reliability.
