Two-current correlations in the pion on the lattice

Two-current correlations in the pion on the lattice

Abstract We perform a systematic study of the correlation functions of two quark currents in a pion using lattice QCD. We obtain good signals for all but one of the relevant Wick contractions of quark fields. We investigate the quark mass dependence of our results and test the importance of correlat...
