| dc.description.abstract | A signal consistent with the Ωð2012Þ baryon has been observed with a significance of 15σ in pp collisions at (Formula presented) ¼ 13 TeV at the LHC. In this paper, the analysis technique is described and measurements of the mass and width of the Ωð2012Þ are reported, along with the first measurement of its transverse-momentum spectrum and yield. This paper corroborates the observation by the Belle Collaboration of this excited Ω state and the observation that the Ωð2012Þ has a rather narrow width for a strongly decaying resonance. The yield measurement is combined with a statistical thermal model calculation of strange baryon yield ratios to obtain estimates of the Ωð2012Þ− → ΞK̄ branching ratios. These results will improve our understanding of the internal structure and mass spectrum of excited baryon states and serve as a baseline for searches regarding modifications of these properties in high-temperature media. © 2025 CERN, for the ALICE Collaboration | en_US |
