چکیده
This talk summarizes results for all the scale independent renormalization constants for bilinear currents (ZA, ZV , and ZS/ZP ), the improvement constants (cA, cV , and cT ), the quark mass dependence of ZO , and the coefficients of the equation of motion operators for O(a) improved lattice QCD. Using data at β = 6.0, 6.2 and 6.4 we study the scaling behavior of these quantities and quantify residual discretization errors.

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 .
