Using the repeated Laplace transform, we find an analytical solution for Dokshitzer-Gribov-Lipatov- Altarelli-Parisi evolution equations for extracting the pion, kaon, and proton fragmentation functions at next-to-leading-order approximation.We also study the symmetry breaking of the sea quarks fragmentation functions Dh¯qðz;Q2Þ and simply separate them according to their mass ratio. Finally, we calculate the total fragmentation functions of these hadrons and compare them with experimental data and those from global fits. Our results show a good agreement with the fragmentation functions obtained from global parametrizations as well as with the experimental data.
