Very Heavy MSSM Higgs-Boson Production at the Linear Collider
T. Hahn, S. Heinemeyer, G. Weiglein
Abstract
In the Minimal Supersymmetric Standard Model (MSSM) we present the corrections to the heavy neutral CP-even Higgs-boson production in the WW-fusion and Higgs-strahlung channel, e+e- -> nu nu H, taking into account all O(α) corrections arising from loops of fermions and sfermions. While the H boson shows decoupling behavior at the tree-level, we find non-negligible loop corrections that can enhance the cross section considerably. At a center-of-mass energy of s = 1000 GeV, masses of up to MH <= 750 GeV are accessible at the LC in favorable regions of the MSSM parameter space.
