Parity and CP-violation

    I've gained interest in the LHC being built at CERN, which has led me to the LHCb experiments, 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.
