Comment on resummation of mass distribution for jets initiated by massive quarks / U. Aglietti, L. Di Giustino, G. Ferrera, L. Trentadue. - In: PHYSICS LETTERS. SECTION B. - ISSN 0370-2693. - 670:4/5(2009), pp. 367-368.
Abstract:
We compute in the heavy quark effective theory the soft coefficient D2 entering the resummation of next-to-next-to-leading threshold logarithms for jets initiated by a quark with a small mass compared to the hard scale of the process. We find complete agreement with a previous computation in full QCD. Contrary to our previous guess, this coefficient turns out to be different from that one entering heavy flavor decay or heavy flavor fragmentation.
