Abstract / Description:We report a search for charmless hadronic decays of neutral $B$ mesons to $\\eta' K^{*}(892)^{0}$. The results are based on a 711fb$^{-1}$ data sample that contains $772\\times 10^6 B\\overline{B}$ pairs, collected at the $\\Upsilon(4S)$ 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 ${\\cal B}[B^0\\to\\eta' K^{*}(892)^{0}]=[2.6\\pm0.7{\\rm (stat)}\\pm0.2{\\rm (syst)}]\\times 10^{-6}$. We also measure the $CP$ violating asymmetry as ${\\cal A}_{CP}[B^0\\to\\eta' K^{*}(892)^{0}]=-0.22\\pm0.29{\\rm (stat)}\\pm0.07{\\rm syst}$.
