When is the total C-parity of two particles the product?

  1. Jan 16, 2016 #1
    Let's say I have two particles A and B and I want to find the total charge parity of the system ##C_{AB}##. In what cases is it allowed to say ##C_{AB}=C_{A}.C_{B}##?

    I suspect that if A and B are their own antiparticles, then that is OK.

    Is this even the case when the system has a relative angular momentum?

    A and B must be their own antiparticles in order for C[A] and C[ B] to make sense... otherwise the action of charge conjugation will change your eigenstate and so "eigenvalues" won't make much sense...

    yes it is
