Observation of e(+)e(-) annihilation into the C=+1 hadronic final states rho(0)rho(0) and phi rho(0)

Abstract:

We report the first observation of e+e- annihilation into states of positive C parity, namely, ρ0ρ0 and ρ0. The two states are observed in the π+π-π+π- and K+K-π+π- final states, respectively, in a data sample of 225fb-1 collected by the BABAR experiment at the Positron-Electron Project II e+e- storage rings at energies near s=10.58GeV. The distributions of cos θ*, where θ* is the center-of-mass polar angle of the meson or the forward ρ0 meson, suggest production by two-virtual-photon annihil...
