Role of T-odd functions in high energy hadronic collisions

Abstract

I propose a simple model for predicting the enegy behavior of T-odd, chiral odd function $h_1^{\perp }$. Furthermore I illustrate a method for extracting $h_1^{\perp }$ and the transversity function from Drell-Yan. The method may be applied also to other reactions.
