摘要:	We report a study of the decays B -> D(s1)(2536)+ (D) over bar (()()), where (D) over bar (()()) is (D) over bar (0), D(-) or D(-), using a sample of 657 x 10(6)B (B) over bar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The branching fractions of the decays B(+) -> D(s1)(2536)(+) (D) over bar (0), B(0) -> D(s1)(2536)(+)D(-) and B(0) -> D(s1)(2536)(+)D(-) multiplied by that of D(s1)(2536)(+) -> (D(0)K(+) + D(+)K(0)) are found to be (3.97 +/- 0.85 +/- 0.56) x 10(-4), (2.75 +/- 0.62 +/- 0.36) x 10(-4) and (5.01 +/- 1.21 +/- 0.70) x 10(-4), respectively. The ratio B(D(s1) -> D(0)K(+))/B(D(s1) -> D(+)K(0)) is measured to be 0.88 +/- 0.24 +/- 0.08.
