We present a status report on our calculation of the renormalization constants for the quark bilinears in quenched O(a) improved Wilson theory at β = 6.4 using quark states in Landau gauge.

The φa 0 γ-and φσγ-vertices in light cone QCD Abstract We study φa 0 γ-and φσγ-vertices in the framework of the light cone QCD sum rules and we estimate the coupling constants g φa 0 γ and g φσγ utilizing ωφ-mixing. We compare our results with the previous estimations of these coupling constants in the literature obtained from phenomenological considerations .
