摘要
We study hadronic wave functions using an instanton model for the QCD vacuum. The wave functions are defined in terms of gauge invariant Bethe Salpeter amplitudes which we have determined numerically using a Monte Carlo simulation of the instanton ensemble. We find that the pion and the proton, as well as the rho meson and the delta have very similar wave functions but observe a sizeable splitting between mesons or baryons with different spin. We compare our results with data obtained in lattice gauge simulations.
