Explore the Indian participation in the Electron Ion Collider (EIC) project through this informative lecture. Learn about the upcoming EIC facility at Brookhaven National Lab and its potential to revolutionize our understanding of proton and neutron structure. Discover key research questions the EIC aims to address, including quark and gluon distribution in nucleons, the origin of visible matter's mass, proton spin composition, and gluon saturation in heavy ion collisions. Gain insights into the EIC's high luminosity and wide kinematic coverage, which will provide unprecedented access to new information about nucleon structure. Understand the significance of this international collaboration and its impact on advancing particle physics, QCD, hadron physics, and heavy ion physics research.
