Description

We propose to study hard processes and bulk nuclear matter on the same footing in heavy-ion collisions using Glauber modelling of heavy nuclei. To exemplify this approach, we calculate the leading-order corrections to azimuthal decorrelation in Drell-Yan and boson-jet processes due to cold nuclear effects. At leading order in both the hard momentum scale and the nuclear size, the impact-parameter dependent cross section is found to factorize for both processes. The factorization formula involves a convolution of the hard cross section with the medium-modifed initial state parton distributions, and, for the boson-jet production, the medium-modified jet function.
