Abstract

We recall the definitions and the basic properties of the transversity distributions $h^{q,\bar q}_1(x,Q^2)$ and the corresponding nucleon tensor charges $\delta q(Q^2)$ . We briefly comment on different estimates from several phenomenological models and on the future possible measurements with the polarized $pp$ collider at RHIC-BNL. Recent works on the $Q^2$ -evolution of $h^{q,\bar q}_1(x,Q^2)$ are also discussed and their implications on a very useful positivity bound.
