- Аннотация: A measurement of the lifetimes of the and baryons is reported using proton–proton collision data at a centre-of-mass energy of , corresponding to an integrated luminosity of collected by the LHCb experiment. The and baryons are produced directly from proton interactions and reconstructed in the final state. The lifetime is measured to be , and the lifetime is measured to be , where the first uncertainty is statistical, the second systematic, and the third due to the uncertainty on the lifetime. These results confirm previous LHCb measurements based on semileptonic beauty-hadron decays, which disagree with earlier results of a four times shorter lifetime, and provide the single most precise measurement of the lifetime.
