Abstract
An analogy is drawn between the real photons appearing in electrodynamics and the photonlike particle appearing in the dual-resonance model with unit intercept. Sum rules for the Compton scattering of these particles are derived and, by employing the analogy, interpreted in terms of low-energy theorems. In particular we rederive the «universal» property of magnetic moments and the lack of anomalous moments in the dual model. We also show that the Beg-type sum rule exists and is saturated by relatively few states. This is a direct result of the simplicity of the collinear algebra appearing in the dual model.
