Mass and Lifetime measurements at LHCb

The data collected at LHCb during the first run of the LHC are analysed to perform precision measurement of mass and lifetime of hadrons containing heavy quarks. I report here about recent mass measurements of the Ξ⁰_c, Λ⁰_b, Ξ⁻_b, and Ω⁻_b baryons, and of charged and neutral D mesons. Recent precision measurements of the lifetime of λ⁰_b, Ξ⁰_b and Ω⁻_b baryons are also reported. I conclude this report with an overview on the experimental knowledge of the B⁰_s,H, B⁰_s,L, and B⁰_s flavour specific effective lifetimes. LHCb has performed the world best measurements of most of these quantities
