Abstract

We shortly describe the leading twist formalism for spin and transverse-momentum dependent fracture functions recently developed and present results for the production of spinless hadrons in the target fragmentation region (TFR) of SIDIS. In this case not all fracture functions can be accessed and only a Sivers-like single spin azimuthal asymmetry shows up at LO cross-section. Then, we show 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 TFR-would provide access to all 16 leading twist fracture functions. Some particular cases are presented.
