Seeing inside the proton — DIS and the parton model
The experiment the whole field is built on — from detector kinematics to the parton picture. Each section below is a full chapter: complete mathematical treatment, derivations, diagrams, and worked examples.
1.1The experiment and its kinematicsSetup, invariants x, Q², y, W² — derived, with event reconstruction worked in full.
1.2The cross-section and structure functionsLeptonic and hadronic tensors, the F₁/F₂ decomposition derived, Callan–Gross.
1.3Bjorken scaling and the parton modelScaling from point constituents, the infinite-momentum frame, the master formula.
1.4PDFs, sum rules, and flavour structureDefinitions, evolution basis, sum rules derived, proton/deuteron flavour separation.
