Abstract / Description:We report on the first observations of $\\bar{B}^0 \\to D_1(2430)^0 \\omega$, $\\bar{B}^0 \\to D_1(2420)^0 \\omega$ and $\\bar{B}^0 \\to D^*_2(2460)^0 \\omega$ decays. The $\\bar{B}^0 \\to D^{*+} \\rho(1450)^-$ decay is also observed. The branching fraction measurements are based on $(771.6 \\pm 10.6)\\times 10^6$ $B\\bar{B}$ events collected at the $\\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. The fractions of longitudinal polarization of the $D^{**}$ states as well as partial wave fractions of the $D_1(2430)^0$ are obtained. We also set a $90\\%$ confidence level upper limit for the product of branching fractions of $\\mathcal{B}(\\bar{B}^0 \\to D^{*+} b_1(1235)^-) \\times \\mathcal{B}(b_1(1235)^- \\to \\omega \\pi^-)$. The measurements show evidence of nontrivial final-state interaction phases for the $\\rho$-like amplitudes.
