Study of Different Forms for the Recombination Function in the Formation of Mesons from Partons

摘要

The form of the recombination function R is varied phenomenologically, and moment solutions are given for the fragmentation function implied by these different R functions. The fragmentation functions calculated from their moments by the moment inversion method of Yndurain are represented for comparison with experimental data. A description is given of the quark recombination model, and choices are mentioned for the recombination function in meson production, introducing an expression for R and giving a general moment solution for the fragmentation function.
