$\pi \mathrm{\Delta }\mathrm{\Delta }$ coupling constant

We calculate the $\pi \mathrm{\Delta }\mathrm{\Delta }$ coupling $g_{{\pi }^0{\mathrm{\Delta }}^{++}{\mathrm{\Delta }}^{++}}$ using light cone QCD sum rule. Our result is $g_{{\pi }^0{\mathrm{\Delta }}^{++}{\mathrm{\Delta }}^{++}}=(11.8\pm 2.0)$.
