Title: Observation of the decay B 0 → η ' K * ( 892 ) 0

Abstract

In this paper, we report a search for charmless hadronic decays of neutral B mesons to η ' K * ( 892 ) 0 . The results are based on a 711 fb - 1 data sample that contains 772 × 10 6 B B ¯ pairs, collected at the Y ( 4 S ) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider. We observe the decay for the first time with a significance of 5.0 standard deviations and obtain its branching fraction B [ B 0 → η ' K * ( 892 ) 0 ] = [ 2.6 ± 0.7 ( stat ) ± 0.2 ( syst ) ] × 10 - 6 . We also measure the CP -violating asymmetry as A C P [ B 0 → η ' K * ( 892 ) 0 ] = - 0.22 ± 0.29 ( stat ) ± 0.07 ( syst ) .
