2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/112465A vector-dominance two-photon exchange model is proposed to explain the recently observed production of $ρ^0ρ^0$ and $ρ^0ϕ$ 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.7 pages, 2 figures, 1 tableHigh Energy Physics - Phenomenologytext
