Fragmentation functions for gluon into Bc or $$ {B}_c^{\ast } $$ meson

Year: 2022

Type: article

Abstract: In the paper, we calculate the fragmentation functions for g → Bc and g → $$ {B}_c^{\ast } $$ B c ∗ . 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 $$ {D}_{g\to {B}_c} $$ D g → B c (z, μF) and $$ {D}_{g\to {B}_c^{\ast }} $$ D g → B c ∗ (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 $$ \overline{b} $$ b ¯ → Bc( $$ {B}_c^{\ast } $$ B c ∗ ) and c → Bc( $$ {B}_c^{\ast } $$ B c ∗ ).
