Abstract:	摘要： We report on the first observations of B super(-)0 arrow right D1(2430)0 omega , B super(-)0 arrow right D1(2420)0 omega , and B super(-)0 arrow right D2(2460)0 omega decays. The B super(-)0 arrow right D+[rho](1450)- decay is also observed. The branching fraction measurements are based on (771.6+ or -10.6)x106 BB super(-) 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 D1 (2430)0 are obtained. We also set a 90% confidence level upper limit for the product of branching fractions of B(B super(-)0 arrow right D*+b1(1235)-)xB(b1(1235 )- arrow right omega [pi]-). The measurements show evidence of nontrivial final-state interaction phases for the [rho]-meson-like amplitudes. 出版日期： 2015-07-01 出處： Physical review.
