Some Remarks onωandϕMeson Widths andR-Conjugation Invariance in Strong Interaction

Abstract

It is pointed out that partial widths of two neutral vector mesons, $\omega$ and $\varphi$, into three pions provide some information for or against $R$-conjugation invariance in strong interaction. A particular model is considered in detail, in which $\omega$ and $\varphi$ mesons are $R$ conjugation invariantly associated with baryonic charge and hypercharge currents, respectively. This model is shown to explain consistently various phenomena involved in production and decay processes of these vector mesons.
