Single Higgs boson production at future linear colliders including radiative corrections

The next generation of high energy e+e- linear colliders is expected to operate at √s > or approx. 500 GeV. In this energy range the WW fusion channel dominates the Higgs boson production cross section e+e-→ν-barνh0/H0. 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 H0 is also discussed
