摘　　要：In this paper, we compute the relativistic corrections of the fragmentation functions (FFs) for a heavy quark to Bc and Bc^* within the framework of non-relativistic QCD (NRQCD) factorization. The non-singlet and singlet DGLAP evolutions are also presented.In this paper,we compute the relativistic corrections of the fragmentation functions(FFs)for a heavy quark to Bc and Bc* within the framework of non-relativistic QCD(NRQCD)factorization.The non-singlet and singlet DGLAP evolutions are also presented.
