C - invariance

  1. May 8, 2013 #1
    1. The problem statement, all variables and given/known data

    Which of the folowing decays are forbidden by C-iinvariance
    ω° = π° + γ
    η' = ρ° + γ
    π° = γ +γ + γ




    2. Relevant equations
    None

    3. The attempt at a solution
    The answers are meant to be:
    ω° = π° + γ
    -1 : (+1) (-1) -> Allowed
    η' = ρ° + γ
    +1 -> (-1) (-1) -> Allowed

    π° = γ +γ + γ
    +1 -> (-1)(-1)(-1) -> forbidden

    My question is where are those +1 and -1 gotten from, I have tried to find what values to put for the particles but cannot fund them anywhere.
    Does anyone know if the three are right and if so where I can get the +1 or -1?

    You can find the C quantum number at the http://pdglive.lbl.gov/listings1.brl?quickin=Y [Broken], for example. Even Wikipedia should have them...
