Quark spin effects in $e^{+}{e}^{-}$ annihilation: a Monte Carlo event generator study

A. Kerbizi, L. Lönnblad, A. Martin

Quark spin effects in $e^{+}{e}^{-}$ annihilation to pseudoscalar and vector mesons are implemented for the first time in the PYTHIA Monte Carlo event generator. The spin-dependent fragm…
