Two-photon exchange model for production of neutral meson pairs in e+e- annihilation

Abstract

A vector-dominance two-photon exchange model is proposed to explain the recently observed production of ${\rho }^0{\rho }^0$ and ${\rho }^0\varphi$ pairs in $e^{+}{e}^{-}$ annihilation at 10.58 GeV with the BaBar detector. All the observed features of the data --angular and decay distributions, rates-- are in agreement with the model. Predictions are made for yet-unobserved final states.
