The spin-dependent two-loop splitting functions

Abstract

We present a complete description of the calculation of the spin-dependent next-to-leading order splitting functions. The calculation is performed in the light-cone gauge. We give results for different prescriptions for the Dirac matrix ${\gamma }_5$ in $d=4-2ϵ$ dimensions and provide the link to the results in dimensional reduction.
