Recent developments in nucleon spin structure with focus on h_{1L}^{\perp} and pretzelosity h_{1T}^\perp
H. Avakian, A. V. Efremov, P. Schweitzer +2
The leading twist transverse momentum dependent parton distribution functions h_{1L}^{\perp} and h_{1T}^\perp, which is sometimes called "pretzelosity," are studied. For h_{1L}^{\p…

Transversity distribution in spin asymmetries in semi-inclusive DIS and in the Drell-Yan process
A. V. Efremov, K. Goeke, P. Schweitzer
A review is given on single spin asymmetries in deep inelastic semi-inclusive scattering (SIDIS) and their possible theoretical understanding in the framework of QCD-induced factor…
