WebAPPENDIX B FEYNMAN RULES In this Appendix we collect together all of the rules for the calculation of relativis- tic cross sections and decay rates. The rules fall into two parts. … WebEach of the three basic interactions can be described using a symbol called a Feynman vertex. To the particle physicist, each Feynman vertex represents a component of some sophisticated mathematics that is used to calculate various aspects of particle interactions. But we can use the vertices in a non-mathematical way to illustrate how quarks ... gegants antics
