Observation of e+e- --> rho+rho- near sqrt(s)=10.58 GeV

The BABAR Collaboration, B. Aubert

We report the first observation of $e^{+}{e}^{-}\to {\rho }^{+}{\rho }^{-}$, in a data sample of 379 $f{b}^{-1}$ collected with the BABAR detector at the {PEP-II} $e^{+}{e}^{-}$ storage ring at center-of-mass…
