Description
Nucleons (protons and neutrons), composed of quarks held together by gluons, exhibit rapid growth in gluon density towards small momentum fractions (x). It is expected that this growth is controlled by nonlinear Quantum Chromodynamics (QCD) effects leading to the effect of gluon saturation. Understanding the role of saturated strong gluon fields has motivated tremendous theoretical efforts. Gluon saturation in heavy nuclei is predicted to result in suppressed and broader two-particle angular correlation in heavy nuclei involved collisions. Finding definitive evidence for a novel universal regime of nonlinear gluon dynamics is a primary objective of the RHIC Cold QCD Program and the EIC project.
During 2015 and 2016, the STAR experiment collected high luminosity p+p, p+A, and d+A data. In this talk, we will present the recent results of forward di-hadron correlations from those datasets using STAR detectors. Simulation studies on the predicted broadening phenomena will also be discussed.
