Title: Relating meson and baryon fragmentation functions by shower-parton recombination

Abstract

We relate the fragmentation functions of partons into mesons and baryons in the framework of recombination of shower partons. The results are in reasonable agreement with the data. The implication is that the meson and baryon fragmentation functions are not independent when hadronization of the shower partons is taken into account. The conclusion therefore closes a conceptual gap in the system of fragmentation functions, whose Q{sup 2} evolution has been more extensively studied than the interrelationship among various species of hadrons produced.
