Abstract

We calculate the strong coupling constant g ΔN π and study the strong decay Δ++p π with light-cone QCD sum rules. The numerical value of the strong coupling constant g ΔN π is consistent with the experimental data. The small discrepancy may be due to the failure to take into account perturbative \(\mathcal {O}(\alpha_{s})\) corrections.
