Unstable Particles, Gauge Invariance and the Δ++ Resonance Parameters

The elastic and radiative π+p scattering are studied in the framework of an effective Lagrangian model for the Δ++ resonance and its interactions. The finite width effects of this spin-3/2 resonance are introduced in the scattering amplitudes through a complex mass scheme to respect electromagnetic...
