Abstract

We review and update previous calculations of the coupling constants gVσγ and also determine new variables including the magnetic susceptibility of the quark condensate in QCD sum rules. Our estimates are consistent with the values obtained in the literature. © 2013 Pleiades Publishing, Ltd.
