The Longitudinal Heavy Quark Structure Function F_{L}^{Q\bar{Q}} in the Region Q^2 \gg m^2 at O(α_s^3)

Authors

Description

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