Fragmentation Functions of neutral mesons ${\pi }^0$ and $k^0$ with Laplace transform approach

Abstract

With an analytical solutions of DGLAP evolution equations based on the Laplace transform method , we find the fragmentation functions (FFs) of neutral mesons, ${\pi }^0$ and $k^0$ at NLO approximation. We also calculated the total fragmentation functions of these mesons and compared them with experimental data and those from global fits. The results show a good agreements between our solutions and other models and also are compatible with experimental data.
