Abstract:	摘要： We report the first observation of the decay (ProQuest: Formulae and/or non-USASCII text omitted) using a 980fb super(-1) data sample collected by the Belle detector at the KEKB asymmetric-energy e super(+)e super(-) collider. This is the first observation of a doubly Cabibbo-suppressed decay of a charmed baryon. We measure the branching ratio of this decay with respect to its Cabibbo-favored counterpart to be (ProQuest: formulae and/or non-USASCII text omitted), where the (2.35+ or -0.27+ or -0.21)x10-3 uncertainties are statistical and systematic, respectively. 出版日期： 2016-07-01 出處： Physical review letters, 2016-07, Vol.117 (1) 資源來源： American Physical Society Journals 識別號： ISSN: 0031-9007 識別號： EISSN: 1079-7114 識別號： DOI: 10.1103/PhysRevLett.117.011801
