I just read that the rho mesons have the same quark content as pions, but with one net unit angular momentum. Is their higher energy due to the energy associated with their angular momentum?
(A short 'rigid rotor' calculation indicated a size of the order 10^-15m to 10^-11m depending on whether using the mass of a u/d quark or half the pion mass, which seems reasonable)
PS: I saw delta+ and delta 0 particles have the same quark content as the proton and the neutron, are these also excited states?
