Abstract
We present new sets of fragmentation functions for charged pions and kaons, both at leading and next-to-leading order. They are fitted to TPC data taken at energy {radical}s=29 GeV and describe excellently a wealth of other e{sup +}e{sup -} data on charged-hadron production, ranging from {radical}s=5.2 GeV way up to LEP 1 energy. They also agree with data on the production of neutral pions and kaons, if one makes the natural assumption that the respective fragmentation functions are related to the charged counterparts by SU(2) symmetry. We also list simple parameterizations of the x and Q{sup 2} dependence of our results, which may be implemented conveniently in applications. (orig.)
