Abstract
We consider the computation of D and B fragmentation functions in e(+)e(-) annihilation. We compare the results of fitting present data using the next -to-leading-logarithmic resummed approach, versus the O(alpha(s)(2)) fixed- order calculation, including also mass-suppressed effects. We also propose a method for merging the fixed-order calculation with the resummed approach . (C) 2000 Elsevier Science B.V. All rights reserved.
