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

e^+e^-

linear machines [including the

\gamma \gamma

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

h \tilde{t} \tilde{t}

coupling, the potentially largest coupling in the supersymmetric theory.
