Explore the intricacies of hadron structure through light-front quark models in this 30-minute lecture by Harleen Dahiya. Delivered as part of the International School and Workshop on Probing Hadron Structure at the Electron-Ion Collider, this talk delves into the fundamental aspects of quark dynamics within hadrons. Gain insights into how light-front quark models contribute to our understanding of hadron structure, a crucial component in preparing for the upcoming electron-ion collider experiments at Brookhaven National Lab. Learn about the theoretical frameworks used to describe quark distributions, their role in hadron mass generation, and how these models relate to key questions in particle physics, such as the spin structure of protons and the distribution of quarks and gluons within nucleons.
