Yukawa Interaction

  1. Nov 9, 2006 #1
    I have been trying to independently learn quantum field theory, and I've been stumped on a few points....

    Suppose I had an interacting Lagrangian with the following form:

    L = H(x) PsiBar(x) (a + i b gamma5) Psi(x)

    where:

    H(x) is a field in which the Hermiticity condition is imposed,
    Psi(x) and PsiBar(x) are the field operators,
    a and b are constants,
    and gamma5 is the axial "gamma 5" matrix

    Exactly what constraints would the Hermiticity condition impose?

    Also, how would this expression transform under C, P, T, CP and CPT?

    Thanks.
