γ5-invariant equations for a massive particle
Abstract
A pair of γ5-invariant equations for a massive particle with helicity defined in the rest frame is constructed. Unlike the Feynman-Gell-Mann equation in the absence of electromagnetic fields, these equations are not equivalent to the Klein-Gordon equation.
