MSSM charged Higgs production in the 1 TeV domain and large tan β determination

摘要

In the last few years, considerable effort has been devoted to the study of elec-troweak effects in pair production at future lepton colliders, since, within the SM, for c.m. energies of a few TeV size, it has been realized [1,2] that unexpectedly large virtual effects arise at the one-loop level. These terms have the analogous dependence on energy as those originally determined in QED by Sudakov [3]; at one loop, they can either be of squared logarithmic (leading) (DL) or of linear logarithmic (subleading) (SL) kind.
