On gamma_5 in higher-order QCD calculations and the NNLO evolution of the polarized valence distribution
S. Moch, J. A. M. Vermaseren, A. Vogt
We discuss the prescription for the Dirac matrix gamma_5 in dimensional regularization used in most second- and third-order QCD calculations of collider cross sections. We provide…
The Three-Loop Splitting Functions in QCD: The Helicity-Dependent Case
S. Moch, J. A. M. Vermaseren, A. Vogt
We present the next-to-next-to-leading order (NNLO) contributions to the main splitting functions for the evolution of longitudinally polarized parton densities of hadrons in pertu…
A calculation of the three-loop helicity-dependent splitting functions in QCD
A. Vogt, S. Moch, J. A. M. Vermaseren
We have calculated the complete matrix of three-loop helicity-difference (`polarized') splitting functions Delta P_ik^(2), i,k = q,g, in massless perturbative QCD. In this note we…
On higher-order flavour-singlet splitting and coefficient functions at large x
A. Vogt, G. Soar, S. Moch +1
We discuss the large-x behaviour of the splitting functions P_qg and P_gq and of flavour-singlet coefficient functions, such as the gluon contributions C_2,g and C_L,g to the struc…
