| 摘要: | 摘要: We report the observation of two narrow structures in the mass spectra of the π(±)Υ(nS) (n=1, 2, 3) and π(±)h(b)(mP) (m=1, 2) pairs that are produced in association with a single charged pion in Υ(5S) decays. The measured masses and widths of the two structures averaged over the five final states are M(1)=(10,607.2±2.0) MeV/c2, Γ(1)=(18.4±2.4) MeV, and M(2)=(10,652.2±1.5) MeV/c2, Γ(2)=(11.5±2.2) MeV. The results are obtained with a 121.4 fb(-1) data sample collected with the Belle detector in the vicinity of the Υ(5S) resonance at the KEKB asymmetric-energy e+ e- collider. 其他題名: Phys Rev Lett 出版者: United States: American Physical Society 出版日期: 2012-03-23 出處: Physical review letters, 2012-03, Vol.108 (12), p.122001, Article 122001 資源來源: American Physical Society Journals 識別號: ISSN: 0031-9007 識別號: ISSN: 1079-7114 識別號: EISSN: 1079-7114 識別號: DOI: 10.1103/PhysRevLett.108.122001 識別號: PMID: 22540572 |
