Monte Carlo approach to multiparticle production in a quark-parton model. III. e+e- annihilation and quark fragmentation functions
- 1. Department of Theoretical Physics, Comenius University, Bratislava, Czechoslovakia
Description
A Monte Carlo quark-parton model of multiparticle production in e+e- annihilation is presented. The model is based on the assumption that the polarization cloud in e+e- annihilation behaves in a similar way as the parton system near y* approx. = 0 in hadronic collisions. The model is constructed in a close analogy with our previous work on multiple production in hadron collisions. With all the parameters fixed by data on hadron collisions the model gives reasonable results for e+e- annihilation. Quark fragmentation functions are extracted from our results on particle production in e+e- annihilation. Our results for fragmentation of quarks to mesons are similar to those obtained reecently by Field and Feynman in a different model. Scale breaking of quark fragmentation functions following from our model is discussed. Predictions for fragmentation of quarks to baryons are presented
