Sign of the Proton-Neutron Mass Difference and a Ghost Scalar Meson

Abstract

A new interpretation of the proton-neutron mass difference has been given independently by Pagels [1] and Fried and Truong [2]. In this note, it is shown that, if this model works, it implies a ghost scalar meson with T=1 and G=-1. Use is made of the technique of spontaneous symmetry-breaking theory [3]. By identifying the ghost with that of the Regge-pole model, one can crudely estimate the magnitude of the feedback by means of a linear extrapolation.
