| 英文摘要 | We study the three-body charmed baryonic decays B-0 ->Sigma(++)(c)p pi(-) and B-0 ->Sigma(0)(c)p pi(+) in the four-body final state B-0 ->Lambda(+)(c)p pi(+)pi(-), using a data sample of 357 fb(-1) accumulated at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We measure the branching fractions B(B-0 ->Sigma(c)(2455)(++)p pi(-))=(2.1 +/- 0.2 +/- 0.3 +/- 0.5)x10(-4), B(B-0 ->Sigma(c)(2455)(0)p pi(+))=(1.4 +/- 0.2 +/- 0.2 +/- 0.4)x10(-4) and B(B-0 ->Sigma(c)(2520)(++)p pi(-))=(1.2 +/- 0.1 +/- 0.2 +/- 0.3)x10(-4) with signal significances of 13.1 sigma, 9.4 sigma and 7.1 sigma, respectively. The errors are statistical, systematic, and due to the uncertainty in B(Lambda(+)(c)-> pK(-)pi(+)), respectively. We also set an upper limit B(B-0 ->Sigma(c)(2520)(0)p pi(+))< 0.38x10(-4) at the 90% confidence level. In addition, we obtain a nonresonant branching fraction of (6.4 +/- 0.4 +/- 0.9 +/- 1.7)x10(-4), and a total branching fraction of (11.2 +/- 0.5 +/- 1.4 +/- 2.9)x10(-4) for B-0 ->Lambda(+)(c)p pi(+)pi(-). |
