Description
The string+3P0 model of spin-dependent hadronization is extended to include the production and decay of polarized spin-1/2 baryons alongside pseudoscalar and vector mesons, and it is implemented in the Pythia event generator for the simulation of deep inelastic scattering (DIS).
The model is used to investigate the spontaneous polarization of lambda, antilambda and other hyperons produced in current and target fragmentations in DIS events with an unpolarized proton target. Large effects are observed in the target fragmentation region calling for measurements feasible using available data from fixed target experimental facilities that can enlighten our understanding of the quark spin dependence of hadronization.
