Studies of $e^+e^-$ annihilations into vector-vector final states
ORAL
Abstract
The observation of the exclusive reaction $e^+e^-\rightarrow \phi \rho$ will be reported. The final state C-parity configuration and the production angle distribution suggest that this is produced through a two-virtual-photon annihilation process. The cross section for this process at $\sqrt s=10.58~GeV $ based on approximately $230~{\rm fb}^{- 1}$ of BaBar data will be reported. We also report results of searches for other exclusive processes, such as $e^+e^-\rightarrow \phi \phi$, in the same data set.
