γ^{5}invariant equations for a massive particle
Abstract
A pair of γ^{5}invariant equations for a massive particle with helicity defined in the rest frame is constructed. Unlike the FeynmanGellMann equation in the absence of electromagnetic fields, these equations are not equivalent to the KleinGordon equation.
