Collins effect and single spin azimuthal asymmetries in the HERMES and COMPASS experiments
A. V. Efremov, K. Goeke, P. Schweitzer
Predictions are made for single spin azimuthal asymmetries due to the Collins effect in pion production from semi-inclusive deeply inelastic scattering off transversely and longitu…

Sivers vs. Collins effect in azimuthal single spin asymmetries in pion production in SIDIS
A. V. Efremov, K. Goeke, P. Schweitzer
Recently it has been argued that the transverse momentum dependent twist-2 Sivers distribution function does not vanish in QCD. Therefore both, the Collins and Sivers effects, shou…
