Abstract

In this talk, we consider the computation of D and B fragmentation functions in e+e- annihilation. We present an improved differential cross section that merges together the O(alpha_s²) fixed-order calculation and the next-to-leading-logarithmic resummed one. We compare the results of fitting present data using the next-to-leading-log cross section, the O(alpha_s²) fixed-order and the improved one.
