TL;DR
This paper introduces a formalism for spin and transverse-momentum dependent fracture functions in SIDIS, showing how double hadron production can access all leading twist fracture functions, advancing understanding of nucleon structure.
Contribution
It develops a leading twist formalism for spin and transverse-momentum dependent fracture functions and demonstrates how double hadron production in polarized SIDIS accesses all 16 leading twist fracture functions.
Findings
Double hadron production in polarized SIDIS accesses all 16 leading twist fracture functions.
The formalism describes spin and transverse-momentum dependence in fracture functions.
Potential to improve understanding of nucleon spin structure.
Abstract
The recently developed leading twist formalism for spin and transverse-momentum dependent fracture functions is shortly described. We demonstrate that the process of double hadron production in polarized SIDIS -- with one spinless hadron produced in the current fragmentation region (CFR) and another in the target fragmentation region (TFR) -- would provide access to all 16 leading twist fracture functions. Some particular cases are presented.
