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

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

A vector-dominance two-photon exchange model is proposed to explain the recently observed production of ρ0ρ0\rho^0\rho^0 and ρ0ϕ\rho^0\phi pairs in e+ee^+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.
