Inclusion of the $^3P_0$ model in PYTHIA 8

High Energy Physics - Phenomenology 2019-09-06 v1

Abstract

The spin effects in the hadronization process have been included for the first time in the PYTHIA 8 event generator. The spin effects are limited to the production of pseudo-scalar mesons and are obtained from the propagation of the quark polarization along the fragmentation chain according to the rules of the so-called 3P0^3P_0 model. The interface between PYTHIA 8 and the package of the 3P0^3P_0 model is presented together with preliminary results on the Collins and di-hadron asymmetries as obtained from simulations of the transversely polarized semi-inclusive deep inelastic scattering process.
