Description
Observation of $B^+ \to \bar{K}{}^{*0}(892)K^+$ at Belle
We present a measurement of the branching fraction for the process $B^+ \to \bar{K}{}^{*0}(892)(\to K^-\pi^+)K^+$ based on a data sample of $657 \times 10^6$ $\Upsilon(4S) \to B\bar{B}$ events collected with the Belle detector at the KEKB $e^+e^-$ asymmetric-energy collider. A measurement of the charge asymmetry of $A_{CP}$ for this process is also presented.
Measurement of $B^0 \to K^+\pi^- K^-\pi^+$ Decays and Search for $B^0 \to K^{*0} \bar K^{*0}$ and $B^0 \to K^{*0} K^{*0}$
We report on a search for the decay $B^0 \to K^{*0} \bar K^{*0}$ and $B^0 \to K^{*0} K^{*0}$ and other charmless modes with a final $K^+\pi^- K^-\pi^+$ state. These results are obtained from a data sample containing $657 \times 10^6$ $B \bar B$ pairs collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider.
Search for $B \to \phi \pi$ decays at Belle
We search for the charmless decays $B^+ \to \phi \pi^+$ and $B^0 \to \phi \pi^0$, which proceed through an external electroweak penguin diagram in the Standard Model. The analysis is based on a data sample of 657 million $B\bar{B}$ pairs collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB $e^+e^-$ storage ring.
