DeltapiN coupling constant in light cone QCD sum rules

Show affiliations


We employ the light cone QCD sum rules to calculate DeltapiN 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.
