Abstract:	摘要： (ProQuest: ... denotes formulae and/or non-USASCII text omitted) We report results of a study of doubly charmed baryons and charmed strange baryons. The analysis is performed using a 980 fb super(-1) data sample collected with the Belle detector at the KEKB asymmetric-energy e super(+)e super(-) collider. We search for doubly charmed baryons ... with the ... and ... final states. No significant signal is observed. We also search for two excited charmed strange baryons, [Xi] sub(c)(3055) super(+) and [Xi] sub(c)(3123) super(+) with the ... and ... final states. The [Xi] sub(c)(3055) super(+) signal is observed with a significance of 6.6 standard deviations including systematic uncertainty, while no signature of the [Xi] sub(c)(3123) super(+) is seen. We also study properties of the [Xi] sub(c)(2645) super(+) and measure a width of 2.6 + or - 0.2(stat) + or - 0.4(syst) MeV /c super(2), which is the first significant determination. 出版者： United States: American Physical Society (APS) 出版日期： 2014-03-17 出處： Physical Review.
