Mellin Representation for the Heavy Flavor Contributions to Deep Inelastic Structure Functions
We derive semi--analytic expressions for the analytic continuation of the
Mellin transforms of the heavy flavor QCD coefficient functions for neutral
current deep inelastic scattering in leading and next-to-leading order to
complex values of the Mellin variable . These representations are used in
Mellin--space QCD evolution programs to provide fast evaluations of the heavy
flavor contributions to the structure functions and
