摘要：
We present a leading order (LO) estimate for the longitidinal-transverse spin asymmetry (A(LT)) in the nucleon-nucleon polarized Drell-Yan process at RHIC and HERA-(N) over right arrow energies in comparison with A(LL) and A(TT). A(LT) receives contribution from g(1), the transversity distribution hi, and the twist-3 distributions g(T) and h(L). For the twist-3 contribution we use the lag model prediction evolved to a high energy scale by the large-iii, evolution equation. We found that A(LT) (normalized by the asymmetry in the parton level) is much smaller than the corresponding A(TT) Twist-3 contribution given by the bag model turned out to be negligible.
