A Search for Charmless $B\to VV$ Decays

Abstract

We have studied two-body charmless decays of the $B$ meson into the final states ${\rho }^0{\rho }^0$, $K^{\ast 0}{\rho }^0$, $K^{\ast 0}{K}^{\ast 0}$, $K^{\ast 0}\overline{K^{\ast 0}}$, $K^{\ast +}{\rho }^0$, $K^{\ast +}\overline{K^{\ast 0}}$, and $K^{\ast +}{K}^{\ast -}$ using only decay modes with charged daughter particles. Using 9.7 million $B\bar{B}$ pairs collected with the CLEO detector, we place 90% confidence level upper limits on the branching fractions, $(0.46-7.0)\times 10^{-5}$, depending on final state and polarization.
