Why have I not seen equations that would tell the masses of hadrons as functions of other constants, like masses of quarks, and some coupling constants? After all, aren't the different hadrons merely different excitation states of some bound systems, and in principle it should be possible to calculate the excitation energies (particle masses) like the energies of the hydrogen atom?
Is it because the equations are too difficult, or because physicists don't know what kind of equation to write down? The standard model is supposed to be the theory of particle interactions, so it sounds like we should know what equation to use for the hadron masses, but is that really the case?
