title = "Measurement of the lifetimes of promptly produced Ω c 0 and Ξ c 0 baryons",
abstract = "A measurement of the lifetimes of the Ω c 0 and Ξ c 0 baryons is reported using proton–proton collision data at a centre-of-mass energy of 13TeV, corresponding to an integrated luminosity of 5.4fb -1 collected by the LHCb experiment. The Ω c 0 and Ξ c 0 baryons are produced directly from proton interactions and reconstructed in the pK -K -π + final state. The Ω c 0 lifetime is measured to be 276.5±13.4±4.4±0.7fs, and the Ξ c 0 lifetime is measured to be 148.0±2.3±2.2±0.2fs, where the first uncertainty is statistical, the second systematic, and the third due to the uncertainty on the D 0 lifetime. These results confirm previous LHCb measurements based on semileptonic beauty-hadron decays, which disagree with earlier results of a four times shorter Ω c 0 lifetime, and provide the single most precise measurement of the Ω c 0 lifetime.",
