Spatially dependent parton distribution functions and hard processes in nuclear collisions

TL;DR

This paper investigates the spatial dependence of nuclear parton distribution functions and their impact on hard particle production in nuclear collisions at RHIC and LHC, using perturbative QCD and collinear factorization.

Contribution

It introduces a framework for incorporating spatial dependence into nuclear PDFs and examines their effects on high-energy collision processes.

Findings

Spatially dependent nPDFs influence particle yields in nuclear collisions.

Application of pQCD and collinear factorization to nuclear PDFs at collider energies.

Abstract

This work focuses on applications of perturbative QCD (pQCD) and collinear factorization theorem to hard particle production in nuclear and hadronic collisions at the BNL-RHIC and CERN-LHC colliders. The emphasis is on nuclear parton distribution functions (nPDFs) and their spatial dependence. Also parton-to-hadron fragmentation functions (FFs) are studied. A brief overview of the applied theoretical and numerical tools is given in the introductory part.
