Evidence for the decay Ω0c→π+Ω(2012)−→π+(¯KΞ)−
Using a data sample of 980 fb(-1) collected with the Belle detector operating at the KEKB asymmetricenergy e(+)e(-) collider, we present evidence for the Omega(2012)-in the resonant substructure of Omega(0)(c) -> pi(+)(<(K)over bar Xi)(-) decays. The significance of the Omega(2012)-signal is 4...

| Resumo: | Using a data sample of 980 fb(-1) collected with the Belle detector operating at the KEKB asymmetricenergy e(+)e(-) collider, we present evidence for the Omega(2012)-in the resonant substructure of Omega(0)(c) -> pi(+)(<(K)over bar Xi)(-) decays. The significance of the Omega(2012)-signal is 4.2s after considering the systematic uncertainties. The ratio of the branching fraction of O degrees c -> p(+) Omega(0)(c) -> pi(+)(<(K)over bar Xi)(-) -relative to that of O degrees c. p(+) O-is calculated to be 0.220 similar to 0.059. The individual ratios of the branching fractions of the two isospin modes are also determined and found to be Omega(0)(c) -> pi(+)(<(K)over bar Xi)(-) = o9.6 similar to Omega(0)(c) -> pi(+)(<(K)over bar Xi)(-) +/- 0.7(syst))%. |
