A new approach to semi-inclusive deep-inelastic scattering with QED and QCD factorization

Abstract We present the details of a new factorized approach to semi-inclusive deep-inelastic scattering which treats QED and QCD radiation on equal footing, and provides a systematically improvable approximation to the extraction of transverse momentum dependent parton distributions. We demonstrate...
