Problem Set 4
Due: Monday, March 12th
1. Neutral Kaon Oscillations. If we collide a - beam on a nuclear target we can produce a pure K 0 beam through the associated production - p 0 K 0 . Let |(t) be a state that is pure K 0 at t

Problem Set 5
Due: Monday, April 16th
1. Alternative Landscapes: A world of spinless electrons and muons. If electrons and muons were spinless the calculation of e+ e- + - becomes much simpler. Instead of Dirac spinors u, u, v, an
