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