Relativistic corrections to heavy quark fragmentation to S-wave heavy mesons
发表期刊PHYSICAL REVIEW D
关键词z(0) Decay Annihilation Qcd
摘要The relativistic corrections of order v(2) to the fragmentation functions for the heavy quark to S-wave heavy quarkonia are calculated in the framework of the nonrelativistic quantum chromodynamics factorization formula. We derive the fragmentation functions by using the Collins-Soper definition in both the Feynman gauge and the axial gauge. We also extract them through the process Z(0)-> Hqq in the limit M(Z)/m ->infinity. We find that all results obtained by these two different methods and in different gauges are the same. We estimate the relative size of the relativistic corrections to the fragmentation functions.
