Observation of the decay $B^0\to {\eta }^{\prime }{K}^{\ast }(892{)}^0$

Belle Collaboration, S. Sato, Y. Yusa +161

We report a search for charmless hadronic decays of neutral $B$ mesons to ${\eta }^{\prime }{K}^{\ast }(892{)}^0$. The results are based on a 711fb${}^{-1}$ data sample that contains $772\times 10^6 B\o…
