The polarized two-loop massive pure singlet Wilson coefficient for deep-inelastic scattering

We calculate the polarized massive two–loop pure singlet Wilson coefficient contributing to the structure functions g1(x,Q2) analytically in the whole kinematic region. The Wilson coefficient contains Kummer–elliptic integrals. We derive the representation in the asymptotic region Q2≫m2, retaining p...
