Description

We present our work on the inclusion of spin effects in the hadronization part of the PYTHIA 8 event generator. These effects are restricted to the emission of pseudoscalar mesons and are obtained from the propagation of the quark polarization along the fragmentation chain according to the rules of the ${}^3P_0$ model.
The interface between PYTHIA 8 and the ${}^3P_0$ model and the results on the Collins asymmetry obtained from simulations of the polarized SIDIS process are presented.
