SIDIS in the target fragmentation region: polarized and transverse momentum dependent fracture functions

Abstract

The target fragmentation region of semi-inclusive deep inelastic scattering is described at leading twist, taking beam and target polarizations into account. The formalism of polarized and transverse-momentum dependent fracture functions is developed and the observables for some specific processes are presented.
