Fragmentation functions for gluon into P-wave Bc mesons

A bstract We calculate the fragmentation functions for a gluon into P -wave B c mesons within the nonrelativistic QCD factorization framework, incorporating color-singlet and color-octet contributions. Ultraviolet divergences arising from phase-space integrals are removed via operator renormalization in the modified minimal subtraction scheme. The resulting fragmentation functions are presented in both graphical form and as fitted analytic expressions.
