On the Spectacular Large Asymmetry in $\pbarppipi$ and $\pbarpKK$ Reactions}

Abstract

An illustrative analysis is presented to show the origin of the energy-independent maximal asymmetry observed for wide ranges of angles in the reactions $\pbarppipi$ and $\pbarpKK$. % The general nature of our simple relation between helicity -flip and -nonflip partial wave amplitudes enforces the notion that % these features of the asymmetry for these two annihilation reactions are likely to persist within the hadronic regime. % At higher energies these features of the asymmetry will probably be modified significantly, signaling the onset of perturbative QCD. % Our study supports the arguments that the final $\KbarK$ state originates from a more central reaction than the $\pipi$ final state.
