Abstract
In the supersymmetry (SUSY) models, because of the mass difference bet ween the left-and right-top squarks, the supersymmetric QCD interactio ns can generate parity violating effects in the production of tt pairs . We show that SUSY QCD radiative corrections to the parity violating asymmetry in the production rates of the left-and right-handed top qua rks via the q (q) over bar --> t (t) over bar process can reach about 3% at the Fermilab Tevatron with root s = 2TeV. This could be observab le with an integrated luminosity larger than 2fb(-1). We also show tha t in these models the SUSY QCD radiative corrections to the tit produc tion rate are small unless gluinos are very light, of the order of 1 G eV.
