$\Delta \pi N$ coupling constant in light cone QCD sum rules

Abstract

We employ the light cone QCD sum rules to calculate $\Delta \pi N$ coupling constant by studying the two point correlation function between the vacuum and the pion state. Our result is consistent with the traditional QCD sum rules calculations and it is in agreement with the experimental value.
