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

TL;DR

This paper develops a formalism for polarized and transverse-momentum dependent fracture functions in semi-inclusive deep inelastic scattering, focusing on the target fragmentation region and including polarization effects.

Contribution

It introduces a new formalism for polarized and transverse-momentum dependent fracture functions in the target fragmentation region of SIDIS.

Findings

Formalism for polarized fracture functions developed

Observables for specific processes presented

Inclusion of beam and target polarization effects

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.
