Supersymmetric QCD corrections to lightest Higgs boson associated production with top quark pair at Linear Colliders

Abstract

Supersymmetric (SUSY) QCD corrections to the lightest neutral Higgs boson associated production with top quark pair are studied in the minimal supersymmetric standard model (MSSM) at Linear colliders. Our calculations show that the SUSY QCD effects generally are very moderate (say 10%) and under control, except for some rescattering effects which lead to a breakdown of perturbation theory and require a more detailed study. In the vicinity of the production threshold for the favorable model parameters under the framework of the on-shell renormalization scheme, SUSY QCD can be as large as about -50%. Such effects might be acted as the probe to determine the sign of $M_{LR}\equiv A_t-\mu /\tan \beta$.
