Sivers effect in Drell Yan at RHIC
J. C. Collins, A. V. Efremov, K. Goeke +5
On the basis of a fit to the Sivers effect in deep-inelastic scattering, we make predictions for single-spin asymmetries in the Drell-Yan process at RHIC.

Sivers effect in semi-inclusive deeply inelastic scattering
J. C. Collins, A. V. Efremov, K. Goeke +3
The Sivers function is extracted from HERMES data on single spin asymmetries in semi-inclusive deeply inelastic scattering. Our analysis use a simple Gaussian model for the distrib…

Sivers effect in semi-inclusive DIS and in the Drell-Yan process
A. V. Efremov, K. Goeke, S. Menzel +2
The Sivers parton distribution has been predicted to obey a particular ``universality relation'', namely to have opposite sign in semi-inclusive deeply inelastic scattering (SIDIS)…
