Abstract

Unlike the Review of Particle Physics, the clear nonzero values of the mass and width differences of the neutral and charged [Formula: see text] mesons are determined by an application of the Unitary & Analytic model of the pion electromagnetic and the pion weak form factor in a description of the data on [Formula: see text] and [Formula: see text] processes, respectively. Also the mass and the width differences of the neutral and charged [Formula: see text] and [Formula: see text] mesons are determined for the first time, however, they are masked by large evaluated errors. Therefore, in order to come to a definite conclusion, more precise data on [Formula: see text] and [Formula: see text] in the region of [Formula: see text] and [Formula: see text] mesons are desirable.
