Abstract:

A measurement of the Λb0 lifetime and mass in the decay channel Λb0→J/ψ(μ + μ - )Λ0(pπ - ) is presented. The analysis uses a signal sample of about 2200 Λb0 and Λ̄b0 decays that are reconstructed in 4.9 fb - 1 of ATLAS pp collision data collected in 2011 at the LHC center-of-mass energy of 7 TeV. A simultaneous mass and decay time maximum likelihood fit is used to extract the Λb0 lifetime and mass. They are measured to be τ Λb =1.449±0.036(stat) ±0.017(syst) ps and m Λb =5619.7±0. 7(stat)±1.1(syst) MeV. © 2013 CERN
