Radiative Delta -> N gamma decay in light cone QCD

The g(Delta N gamma) coupling for the Delta-->N gamma decay is calculated in the framework of the light cone QCD sum rules and is found to be g(Delta N gamma)=(1.6+/-0.2) GeV-1. Using this value of g(Delta N gamma) we estimate the branching ratio of the Delta(+)-->N gamma decay, which is in a very good agreement with the experimental result. [S0556-2821(99)02023-8].
