Search for the Decay B0->K*+rho-

TL;DR

This paper reports a preliminary search for the decay B0 to K*+ rho- using data from the BaBar detector, setting an upper limit on its branching fraction due to no significant signal observed.

Contribution

First search for the B0 to K*+ rho- decay mode using BaBar data, establishing an upper limit on its branching fraction.

Findings

No significant signal observed for B0 to K*+ rho- decay.

Upper limit on branching fraction set at 24 x 10^-6 (90% C.L.).

Data analyzed from 123 million B-Bbar pairs.

Abstract

We present the preliminary result of a search for the decay of $B^0\to K^{*+}\rho^-$. The data were recorded with the $BaBar$ detector at the PEPII collider and correspond to 123 million $B\bar{B}$ pairs produced in the $e^+e^-$ annihilation through the $\Upsilon(4S)$ resonance. We obtain an upper limit on the branching fraction for this decay of ${\cal B}(B^0\to K^{*+}\rho^-) <24 \times 10^{-6}$ (90% C.L.). All results are preliminary.
