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 ρ 0 ρ 0 and ρ 0 φ 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.
