N2 - In many superstring-inspired models, the superpartners of the Q = - 1 3, isosinglet quarks (h̃L,R) can have either leptoquark or disquark couplings. The t-channel exchange of the third-generation h̃L,R can contribute to the decays Vt→τ+τ-, bb̄ (where Vt is a 3S1 (tt̄) resonance) with couplings which are, at present, not phenomenologically bounded. We calculate the decays rates for these processes and the forward-backward asymmetries in e+e-→τ+τ-, bb̄ on resonance including such contributions.
