Search for B^{0}→K^{*0}K[over ¯]^{*0}, B^{0}→K^{*0}K^{*0} and B^{0}→K^{+}π^{-}K^{∓}π^{±} decays
2010
We report a search for the decays B-0 -> K*(0)(K) over bar*(0) and B-0 -> KK-0(0) . We also measure other charmless decay modes with K+ pi K--(-)pi(+) and K+pi K--(+)pi(-) final states. The results are obtained from a data sample containing 657 x 10(6) B (B) over bar pairs collected with the Belle detector at the KEKB asymmetric- energy e(+)e(-) collider. We set upper limits on the branching fractions for B-0 -> K*(0)(K) over bar*(0) and B-0 -> KK-0(0) of 0: 81 x 10(-6) and 0.20 x 10(-6), respectively, at the 90% confidence level.
