Measurement of the Ξ−b and Ω−b baryon lifetimes
(Physics Letters B , 2014, Vol. 736, (Setembre), 2014-09-07)Using a data sample of pp collisions corresponding to an integrated luminosity of 3 fb−1, the Ξ−b and Ω−b baryons are reconstructed in the Ξ−b→J/ψΞ− and Ω−b→J/ψΩ− decay modes and their lifetimes measured ...
