The angular momentum controversy: What's it all about and does it matter?
by E. Leader, C. Lorce
Publisher: arXiv 2013
Number of pages: 96
The general question, crucial to an understanding of the internal structure of the nucleon, of how to split the total angular momentum of a photon or gluon into spin and orbital contributions is one of the most important and interesting challenges faced by gauge theories like Quantum Electrodynamics and Quantum Chromodynamics.

These are graduate lecture notes on Quantum Chromodynamics (QCD) and the theory of Electroweak (EW) Interactions, with main focus on Collider Physics. I hope that these lectures can provide an introduction to the subject for the interested reader.

In this course we will learn how to use the computer tools -- such as SARAH, MicrOmegas, MadGraph, SPheno or FlavorKit -- to explore new physics models and get robust numerical predictions to probe them in current and future experiments.
The Standard Model of particle physics is a theory concerning the electromagnetic, weak, and strong nuclear interactions, which mediate the dynamics of subatomic particles. It was developed as a collaborative effort of scientists around the world.
