Hi everyone,
I am curious about how a neutral pion decays in two photons. I don't understand how it is possible since the pion has spin = 1 and the photons have spin = 1 as well: doesn't this mean that spin is not conserved in this decay? What am I missing?
Another question I have is about spin: do anti-particles and anti-quarks have negative spin, or is the spin always positive?
Sorry for the silly questions and thanks to everyone in advance :)
