Homework Statement
Which of the following reactions are forbidden and why?
[itex]\pi^{0}\rightarrow\gamma[/itex]
Homework Equations
None?
The Attempt at a Solution
I'm pretty sure that the decay doesn't occur (it's forbidden) but I don't know why. I know that it decays most of the time into two gammas.
I think the problem is that I don't understand what characteristics [itex]\gamma[/itex] (photon) has. As in, when I do other problems like this I look at the quark content and the flavors, compare Strangeness and Lepton numbers etc etc.
Thanks!
