Instanton effects in heavy lambda masses
We calculate the masses of lambdab and lambdac in the framework of QCD sum rules including instanton contributions. We find that these contributions have the same size of the four quark condensate contribution and improve the Borel stability in both Dirac structures of the baryon correlation function.
