Abstract

A vector-dominance two-photon exchange model is proposed to explain the recently observed production of ρ0ρ0 and ρ0ϕ 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.
