Why isnt there a up,up anti-down baryon?

    There doesnt seem to be anything in the theory of the standard model that says such a baryon couldnt exist, so why dont we see it?

    however, you're certainly right that QCD does not forbid many baryonic-like states (such as the pentaquark) that we (debatably) do not see. Why is that? Who knows...
