QCD and QED Corrections to Higgs Boson Production in Charged Current ep Scattering

First order QCD and leading QED corrections to Higgs boson production in the channel ep → νHX ;H → bb̄ are calculated for the kinematical conditions at LEP ⊗ LHC (√s = 1360GeV) and the interesting mass range 80 < MH < 150GeV. In the DIS scheme the QCD corrections (not including the corrections to the branching ratio, which are well-known) are found to be about 1% for the total cross section and −13% to −10% for the observable cross section as defined by appropriate cuts. The latter results depend on the definition of these cuts. The QED corrections amount to about −5%. 1 This work was supported in parts by the Alexander-von-Humboldt Stiftung and German BMFT under contract number 055ZT91I–01
