Electromagnetic $N-Δ(1232)$ transitions within the point-form of relativistic quantum mechanics
The electromagnetic $N-Δ(1232)$ transition amplitudes are calculated using the point-form of relativistic quantum mechanics. The relativistic effects incorporated in the electromagnetic matrix elements give a good description of the transition amplitudes to the $Δ(1232)$ resonance, reproducing well the $Q^2$ behaviour of the data, apart from the low $Q^2$ one.
