Extended Charge and Indication of a Scale of the Supersymmetry

We propose a simple model of one dimensional extended charge configuration which leads to the sum of propagators of a photon and its supersymmetric partner--photino. A scale of the supersymmetry determined by a parameter l enters into photino's part of a superfield. We construct nonlocal QED using these composed propagators. As the local QED, this theory is gauge invariant and renormalizable. Experimental data on the measurement of the anomalous magnetic moment of leptons gives a strong restriction on the scale of the supersymmetry: l≤4.3·10-20 cm.
