Measurement of the Lambda(0)(b) lifetime and mass in the ATLAS experiment
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.
