How Is CP-Violation Explored in Particle Physics?

[Pythagorean]

I've gained interest in the http://lhc.web.cern.ch/lhc/" , which pertain to CP-violation.

QUESTION #1

What sort of classes/branches would teach/contain 'charge conjugation' and 'parity'?

QUESTION #2

the wiki article on parity states that parity is an operator-

"acting on a state ψ as follows: P ψ(r) = ψ(-r). One must have P^2 ψ(r) = e^(i φ) ψ(r), since an overall phase is unobservable."

I'd be interested to see the proof for P^2, and I'm curious how the overall phase being unobservable justifies this (not even sure I know what is meant by the "over all phase")

MY PHYSICS BACKGROUND

I am up to Chapter 7 in Griffith's QM. There doesn't seem to be a section on 'parity' or 'charge conjugation' in the undergrad book, so I am left to wiki

Q1) See QFT Dirac field,KG charged field etc... electroweak model...
Q2)See wigner theorem... its on unitary operator acting on hilbert spaces that implement a symmetry trasf..

An intro course in high energy/particle physics at the level of Perkins would give you a first glimpse of such a thing.
