Abstract: (arXiv)

We have studied two-body charmless decays of the

B

meson into the final states

\rho^0 \rho^0

,

K^{*0} \rho^0

,

K^{*0} K^{*0}

,

K^{*0} \bar{K^{*0}}

,

K^{*+} \rho^0

,

K^{*+} \bar{K^{*0}}

, and

K^{*+} K^{*-}

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.

electron positron: colliding beams
electron positron: annihilation
Upsilon(10570): electroproduction
B: pair production
B: hadronic decay
vector meson: pair production
rho(770)0
K*(892)
B: branching ratio
upper limit
