Branching Fraction Measurements of Charged B Decays to $K^{*+}K^+K^-, K^{*+}\pi^+K^-, K^{*+}K^+\pi^-$ and $K^{*+}\pi^+\pi^-$ Final States (2007)

Abstract

Branching fraction and asymmetry measurements of charmless $B^+\to K^{*+}h^+_1h^-_2$ (where $h_{1,2}$ = $K$, $\pi$) decays are presented, using a data sample of 232 million $\Upsilon(4S) \to$ $BB$ decays collected with the BaBar detector at the SLAC PEP-II asymmetric-energy $B$ factory. Using a maximum likelihood fit, the following branching fraction results were obtained: ${\cal B}$($B^+ \to K^{*+}K^+ K^-)$ = (36.2 $\pm$ 3.3 $\pm$ 3.6) $\times$ 10$^{-6}$ and ${\cal B}$($B^+$ $\to$ $K^{*+}\pi^+\pi^-$) = (75.3 $\pm$ 6.0 $\pm$ 8.1) $\times$ 10$^{-6}$. Upper limits were set for ${\cal B}$($B^+$ $\to$ $K^{*+}\pi^+ K^-$) $
