Yang's Parity Test for the New Spin-0 Mesons

Abstract

Yang's parity test for general spin-0 mesons applied to the decay sequence $X=\ensuremath{\rightarrow}\ensuremath{\phi}\ensuremath{\phi}\ensuremath{\rightarrow}({K}^{+}{K}^{\ensuremath{-}})({K}^{+}{K}^{\ensuremath{-}})$ leads to maximal parity signature. The correlation function for the azimuthal angle between the two $\ensuremath{\phi}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}$ decay planes is given by $1+\ensuremath{\beta}cos2\ensuremath{\phi}$, where $\ensuremath{\beta}=\ensuremath{-}1$ for pseudoscalar $X$, and $1>~\ensuremath{\beta}>~0$ for scalar $X$.
