Deep-dive study
The conceptual foundation for research on proton structure. Five topics, twenty chapters — each a complete mathematical treatment with derivations, scientifically accurate diagrams, and worked examples.
1
Seeing inside the proton — DIS and the parton model
The experiment the whole field is built on — from detector kinematics to the parton picture.
Open ›
2
QCD essentials — asymptotic freedom, factorization, DGLAP
The three theorems that turn the parton picture into a precision science.
Open ›
3
The global-fitting machine — from measurements to PDFs
The engineering: parametrizations, sum-rule algebra, FK tables, and the χ² done right.
Open ›
4
Bayesian inference for PDFs — posterior, evidence, nested sampling
The statistical engine of this lab, derived from first principles.
Open ›
5
Uncertainty methods — Hessian vs replicas vs Bayesian
Three philosophies for one question, their equivalence theorem, and their failure modes.
