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

J. Blümlein, A. De Freitas, W. L. van Neerven +1

The logarithmic and constant contributions to the Wilson coefficient of the longitudinal heavy quark structure function to $O({\alpha }_s^3)$ are calculated using mass factorization techni…
