Estimates of T-odd distribution and fragmentation functions

Abstract

Estimates of the T-odd fragmentation and distribution functions, $H_1^{\perp }$ and $f_{1T}^{\perp }$, are presented. Our evaluations are based on a fit on experimental data of polarized proton-proton scattering. We use our estimates to make predictions for electron polarized-proton azimuthal asymmetries.
