Issue Date: | 3-Aug-2007 | Publisher: | American Physical Society | Citation: | Physical Review Letters 99(5): 052002 (2007) | Abstract: | We report the observation and measurement of the mass of the bottom, strange baryon Ξ(-)(b) through the decay chain Ξ(-)(b)-->J/Ψ Ξ(-), where J/Ψ --> μ(+)μ(-), Ξ(-) --> Λπ(-), and Λ --> pπ(-). A signal is observed whose probability of arising from a background fluctuation is 6.6x10(-15), or 7.7 Gaussian standard deviations. The Ξ(-)(b) mass is measured to be 5792.9 ± 2.5(stat) ± 1.7(syst) MeV/c^(2). | Description: | 7 páginas, 2 figuras, 1 tabla.-- PACS nrs.: 14.20.Mr, 13.30.Eg, 13.60.Rj.-- CDF Collaboration: et al. | Publisher version (URL): | http://dx.doi.org/10.1103/PhysRevLett.99.052002 | URI: | http://hdl.handle.net/10261/8530 | DOI: | 10.1103/PhysRevLett.99.052002 | ISSN: | 0031-9007 |
