Explore the internal structure of protons through a 33-minute lecture on "Glue and Sea Inside the Proton from a Light-front Hamiltonian" presented by Chandan Mondal at the International Centre for Theoretical Sciences. Delve into the fundamental building blocks of matter as part of the International School and Workshop on Probing Hadron Structure at the Electron-Ion Collider. Gain insights into how quarks and gluons contribute to proton mass and spin, and understand the significance of the upcoming Electron-Ion Collider in advancing our knowledge of nucleon structure. Learn about gluon saturation, color glass condensate, and the unprecedented level of detail the EIC will provide in probing nucleons. Suitable for PhD students, postdocs, and junior faculty members in related fields, this lecture is part of a comprehensive program featuring expert talks, introductory lectures, and opportunities for research presentations.
