Single Higgs boson production at future linear colliders including radiative corrections

Abstract

The next generation of high energy e+ e- linear colliders is expected to operate at \sqrt{s} \gtsim 500 GeV. In this energy range the WW fusion channel dominates the Higgs boson production cross section e+ e- -> \barννh^0/H^0. We calculate the one-loop corrections to this process due to fermion and sfermion loops within the MSSM. We perform a detailed numerical analysis of the total cross section and the distributions of the rapidity, the transverse momentum and the production angle of the Higgs boson. The fermion-sfermion correction is substantial being of the order of -10% and is dominated by the fermion loops. In addition, we explore the possibility of polarized e+ / e- beams. In the so-called "intense coupling" scenario the production of the heavy Higgs boson H^0 is also discussed.
