Abstract

The logarithmic and constant contributions to the Wilson coefficient of the longitudinal heavy quark structure function to $O (I^\pm_{s}^{3})$ are calculated using mass factorization techniques in Mellin space. The small $x$ behaviour of the Wilson coefficient is determined. Numerical illustrations are presented.
