I understand that the pi+ meson is made up of an up and an anti down quark, and the opposite for the pi- meson.
What I'm not really understanding is the makeup of the pi0 quark: http://img219.imageshack.us/i/piol.png/ *Sorry, couldn't get the image tags to work :(*
there is 3 main points I don't get about this:
1. Why does this have 4 quarks whilst plus and minus have two?
2. Why the minus sign, why not a plus?
3. Why the factor of 1/root2 out the front?
I've tried searching on the internet, but I can barely find the makeup of this meson anywhere, let alone an explanation.
Thanks!
