Abstract

Using the formalism of current algebra and PCAC (partially conserved axial-vector current) we calculate the amplitudes for emission of two neutral pions in

\bar{p} p \to K^{+} K^{-}

and in

\bar{p} p \to K^{+} K^{-} K^{+} K^{-}

, and from these the ratios of cross sections

\frac{(\bar{p} p \to K^{+} K^{-} π^{0} π^{0})}{(\bar{p} p \to K^{+} K^{-})}

and

\frac{(\bar{p} p \to K^{+} K^{-} K^{+} K^{-} π^{0} π^{0})}{(\bar{p} p \to K^{+} K^{-} K^{+} K^{-})}

at various energies.
