Abstract:	摘要： We report the analysis of the three-body e super(+)e super(-)[arrowright]BB[pi] super(+ or -), BB[pi] super(+ or -), and BB[pi] super(+ or -) processes, including the first observations of the (ProQuest: Formulae and/or non-USASCII text omitted)(10610)[arrowright][BB+c.c.] super( + or -) and (ProQuest: Formulae and/or non-USASCII text omitted)(10650)[arrowright][BB] super(+ or -) transitions that are found to dominate the corresponding final states. We measure Born cross sections for the three-body production of [sigma](e super(+)e super(-)[arrowright][BB+c.c.] super(+ or -)[pi][- or +])=[17.4+ or -1.6(stat)+ or -1.9(syst)]pb and [sigma](e super(+)e super(-)[arrowright][BB*]+ or -[pi] super([- or +]))=[8.75+ or -1.15(stat)+ or -1.04(syst)]pb and set a 90% C.L. upper limit of [sigma](e super(+)e super(-)[arrowright][BB]+ or -[pi] super([- or +]))<2.9pb. The results are based on a 121.4fb super(-1) data sample collected with the Belle detector at a center-of-mass energy near the [Upsilon](10860) peak. 出版日期： 2016-05-27 出處： Physical review letters, 2016-05, Vol.116 (21) 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.116.212001
