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

Abstract

First order QCD and leading QED corrections to Higgs boson production in the channel $e^{-}p\to \nu H^{0}X;H^0\to b\bar{b}$ are calculated for the kinematical conditions at LEP $\otimes$ LHC ($\sqrt{s}=1360\text{GeV}$) and the interesting mass range $80<M_H<150\text{GeV}$. 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 $-5\%$. Also obtainable with anonymous ftp from gluon.hep.physik.uni-muenchen.de.
