Next to leading order evolution of SIDIS processes in the forward region

We compute the order αs 2 quark initiated corrections to semi-inclusive deep inelastic scattering extending the approach developed recently for the gluon contributions. With these corrections we complete the order αs 2 QCD description of these processes, verifying explicitly the factorization of col...
