Abstract
In the paper, we calculate the fragmentation functions for g → Bc and g → \( {B}_c^{\ast } \). The ultraviolet divergences in the calculation are removed through the renormalization of the operator definition of the fragmentation functions under the modified minimal subtrac- tion scheme. We then obtain the fragmentation functions \( {D}_{g\to {B}_c} \)(z, μF) and \( {D}_{g\to {B}_c^{\ast }} \)(z, μF), which are presented as figures and fitting functions. The obtained fragmentation functions are complementary to the previous work on the next-to-leading order fragmentation functions for \( \overline{b} \) → Bc(\( {B}_c^{\ast } \)) and c → Bc(\( {B}_c^{\ast } \)).
