Elastic and Inelastic Scattering

This lecture covers the concepts of elastic and inelastic scattering in electron-proton interactions at very high momentum transfer. It explains the Rosenbluth expression for elastic scattering, the proton magnetic form factor, and the kinematics of inelastic scattering. The lecture delves into Bjorken scaling, the Callan-Gross relation, and the quark-parton model to describe the structure functions and parton distribution functions within the proton. It also discusses the predictions of the quark-parton model, scaling violations, and the origin of scaling violations. The lecture concludes with a summary of the complex nature of the proton as a sea of quarks and gluons.
