Associated Production of Higgs Bosons with Scalar Quarks at Future Hadron and e+e− Colliders

We analyze the production of neutral Higgs particles in association with the supersymmetric scalar partners of the third generation quarks at future high–energy hadron colliders [upgraded Tevatron, LHC] and ee linear machines [including the γγ option]. In the Minimal Supersymmetric extension of the Standard Model, the cross section for the associated production of the lightest neutral h boson with the lightest top squark pairs can be rather substantial at high energies. This process would open a window for the measurement of the ht̃t̃ coupling, the potentially largest coupling in the supersymmetric theory.
