Title: Evidence for the decay Ω c 0 π + Ω ( 2012 ) π + ( K ¯ Ξ )

Abstract

Using a data sample of 980 fb-1 collected with the Belle detector operating at the KEKB asymmetric-energy e+e- collider, we present evidence for the Ω(2012)- in the resonant substructure of $$Ω^0_c → π^+(\bar{K}Ξ)^- ((\bar{K}Ξ)^- = K^-Ξ^0 + \bar{K}^0Ξ^-)$$ decays. The significance of the Ω(2012)- signal is 4.2σ after considering the systematic uncertainties. The ratio of the branching fraction of $$Ω^0_c →π^+Ω(2012)^- → π^+(\bar{K}Ξ)^-$$ relative to that of $$Ω^0_c → π^+Ω^-$$ is calculated to be 0.220 ± 0.059(stat.) ± 0.035(syst.). The individual ratios of the branching fractions of the two isospin modes are also determined, and found to be $$\mathscr{B}(Ω^0_c → π^+Ω(2012)^-) × \mathscr{B}(Ω(2012)^- → K^-Ξ^0)/\mathscr{B}(Ω^0_c → π^+K^-Ξ^0)$$ = (9.6 ± 3.2(stat.) ± 1.8(syst.))% and $$\mathscr{B}(Ω^0_c → π^+Ω(2012)^-) × \mathscr{B}(Ω(2012)^- →\bar{K}^0Ξ^-)/\mathscr{B}(Ω^0_c →π^+\bar{K}^0Ξ^-)$$ = (5.5 ± 2.8(stat.) ± 0.7(syst.))%.
