Properties of the barycenter of a diffraction-free light beam

This paper is concerned with an observable effect of an unusual quantal degree of freedom that is compatible with the constraint of the transversality condition. The dependence of the barycenter of a diffraction-free light beam on this degree of freedom is investigated.
