Particle Physics HW 9 Quiz                 Name__________________ 

You can try both problems below, but you will only receive credit for the most correct solution.   

 1. a) (6 pts) Consider the process  → .  Considering only the electromagnetic interaction, 

write down the expression for ⟨| | ⟩ to lowest order in terms of momentum dot products. You do not need to show your work, but can instead adapt expressions from your HW as needed.   b) (4 pts) Do the same for  → .   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Turn over for second problem!! 

2)   Evaluate   in terms of dot products such that there are no 

more metric factors in the expression.
