摘要: An accurate knowledge of nuclear parton distribution functions (nPDFs) is an essential ingredient high energy physics calculations when the processes involve nuclei in initial state. It well known now that prompt photon production both hadronic and collisions a powerful tool for exploring densities nucleon nuclei, especially gluon. In this work, we are going to perform comprehensive study isolated $p$-Pb at backward rapidities find best kinematic regions which experimental measurements have most sensitivity modifications densities. Most emphasis will be placed on antishadowing modification. To aim, calculate compare various quantities different values center-of-mass covered by CERN Large Hadron Collider also rapidity realize one useful.
