Q.Peng, B.-Q.Ma

Determination of meson fragmentation functions in the Field-Feynman model

NUCLEAR REACTIONS 1,2H(e-, π+), (e-, π-), (e-, K+), (e-, K-), (e+, π+), (e+, π-), (e+, K+), (e+, K-), E=27.6 GeV or Q2=2.5 GeV2; analyzed meson fragmentation functions using experimental multiplicity data for meson production from HERMES collaboration (Phys. Rev. D 87, 074029 (2011)) in leading order (LO), using Field-Feynman recursive model with extended SU(2) flavor symmetry relations of fragmentation functions; deduced fitting parameters with uncertainties, and fragmentation functions. Comparison with experimental data, and with results of other parametrizations. Discussed SU(2) flavor symmetry breaking effect of meson fragmentation functions.
