The pretzelosity distribution function and intrinsic motion of the constituents in nucleon
Abstract
The pretzelosity distribution function h1T is studied in a covariant the quark-parton model which describes the structure of the nucleon in terms of 3D quark intrinsic motion. This relativistic model framework supports the relation between helicity, transversity and pretzelosity observed in other relativistic models without assuming SU(6) spin-flavor symmetry. Numerical results and predictions for SIDIS experiments are presented.
