Abstract

Yang's parity test for general spin-0 mesons applied to the decay sequence

X = \to ϕ ϕ \to (K^{+} K^{-}) (K^{+} K^{-})

leads to maximal parity signature. The correlation function for the azimuthal angle between the two

ϕ \to K^{+} K^{-}

decay planes is given by

1 + β cos 2 ϕ

, where

β = - 1

for pseudoscalar

X

, and

1 >~ β >~ 0

for scalar

X

.
