The composition of the π0 is (uu_bar - dd_bar/√2; while the composition of the η meson is (uu_bar + dd_bar)/√2. Why is there a - sign in π0 while is there a + sign in η? How are the signs determined?
By the way, can I type Latex symbols on this site? I tried to type the anti up quark by typing \overline{u}, but it did not show what I wanted. How should I type it?
