Title: Observation of an Excited Ω - Baryon

Abstract

Using data recorded with the Belle detector, we observe a new excited hyperon, an Ω* - candidate decaying into Ξ 0K - and Ξ -K$$0\atop{S}$$ with a mass of 2012.4 ± 0.7(stat) ± 0.6(syst) MeV / c 2 and a width of Γ = 6.4$$+2.5\atop{-2.0}$$(stat) ± 1.6(syst) MeV. The Ω* - is seen primarily in Υ(1S), Υ(2S), and Υ(3 S) decays.
