Search for B Meson Decays to omega K*0

TL;DR

This paper reports a search for a specific B meson decay mode to omega K*0, providing an upper limit on its branching fraction based on data collected with the Belle detector, contributing to understanding charmless B decays.

Contribution

First search for B0->omega K*0 decay mode using Belle data, setting an upper limit on its branching fraction.

Findings

Branching fraction measured as 1.2+0.9-0.8 ±0.2 (×10^-6)

Upper limit on branching fraction is <2.7×10^-6 at 90% confidence

No significant signal observed for the decay mode

Abstract

We report a search for the charmless vector-vector decay B0->omega K*0 with 520x10^6 BBbar pairs collected with the Belle detector at the KEKB e+e- collider. We measure the branching fraction in units of 10^-6: Br = 1.2 +0.9-0.8 +-0.2 (<2.7), where the first error is statistical, the second systematic, and the upper limit is at the 90% confidence level.
