Homework Statement
Which of the folowing decays are forbidden by C-iinvariance
ω° = π° + γ
η' = ρ° + γ
π° = γ +γ + γ
Homework Equations
None
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?
