Hadronic decay properties of newly observed Ωc baryons

Hadronic decay properties of newly observed Ωc baryons Hadronic decay widths of the newly observed charmed strange baryons, Ωc(3000)0, Ωc(3050)0, Ωc(3066)0, Ωc(3090)0, and Ωc(3119)0 have been calculated in a P03 model. Our results indicate that Ωc(3066)0 and Ωc(3090)0 can be interpreted as the 1P–wave Ωc2(32-) or Ωc2(52-). Though the measured masses of Ωc(3000)0, Ωc(3050)0, and Ωc(3119)0 are lower than existed theoretical predictions of 1D–wave Ωc, the hadronic decay features of these Ωc favor assignments of the 1D–wave states. Ωc(3000)0 is possibly Ωc1(12+) or Ωc1(32+), Ωc(3050)0 is possibly Ω^c3(52+) or Ω^c3(72+), and Ωc(3119)0 is possibly Ω^c3(52+), Ω^c3(72+), Ωc3(52+) or Ωc3(72+). The predicted total decay widths in these assignments are consistent with experiment under theoretical and experimental uncertainties. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review D American Physical Society (APS)
