RHIC Cold QCD Program

One of the main physics goals of the Relativistic Heavy Ion Collider (RHIC) is to study the structure and QCD dynamics of the nucleon. Its unique capability as the world's only polarized proton collider has produced a wealth of data and provided new insights into the spin structure of the proton. In addition RHIC delivered polarized proton and nucleus collisions in 2015 for the first time which allowed us to explore nuclear effects in spin observables. The RHIC p+p and p+A measurements are also complementary to lepton-nucleus scattering data and therefore provide important tests of fundamental concepts of QCD. This talk will summarize recent highlights of the RHIC cold QCD program. I will also discuss the prospects of the future RHIC measurements and the Electron Ion Collider.
