Abstract：
The pion fragmentation functions are studied in the Field-Feynman recursive model with distinction of Duπ+,Ddπ+ and Dsπ+ , by taking into account the flavor structure in the excitation of the sea quark-antiquark pairs by the initial quarks. The analytical results obtained are compatible with the available empirical results with only three parameters. The framework is also extended to predict the kaon fragmentation functions with distinction of DsK+(z) , DuK+ (z) ,DsK+(z)and DdK+ (z) . This work gives a significant modification to the original model, and the predictions can be tested by further experimental results on kaon fragmentation functions.
