Here is what a good PDF should give you:
Here is a curated guide to the best resources for particle physics problems and solutions. Why Practice Matters in Particle Physics particle physics problems and solutions pdf
A good resource starts with basic quark model assignments and progresses to complex loop calculations. Here is what a good PDF should give
Here is a suggested folder structure for your particle physics PDFs: supplement with university exam banks
These are typically found in PDFs titled "Quantum Field Theory Problems and Solutions" which overlap heavily with particle physics.
The best "particle physics problems and solutions PDF" is the one that challenges your assumptions about the subatomic world. Start with Griffiths, supplement with university exam banks, and never stop calculating. Quark models Electroweak unification , so I can find a more targeted resource?
