Plan for week 4 (Jan. 20 and 22)

We will continue to discuss QED interactions before we move to QCD and discussion of quarks and gluons. We will see how to derive the QCD lagrangian and what implications such a non-abelian gauge theory has in collider experiments. The topics are covered in chapter 9 and 10 in Thomson and chapter 2 in The Standard Model of Electroweak Interactions by A. Pich.

On Wednesday we will work on the CompHep example in Appendix B of High pT Physics at Hadron Colliders by Dan Green.
