E° → E* + Ve + a) Determine the missing particle in the box. Fully justify your choice based on all relevant conservation laws. b) Determine which of the four fundamental forces is most likely responsible for this decay. Fully justify your answer. [HINT: note the quark compositions of the E° particle and of the E* particle.]
