Measurement of the $\Lambda_b^0$ lifetime and mass in the ATLAS experiment
A measurement of the $\Lambda_b^0$ lifetime and mass in the decay channel $\Lambda_b^0\to J/\psi(\mu^+\mu^-) \Lambda^0 (p^+\pi^-)$ is presented here. The analysis uses a signal sample of about 2200 $\Lambda_b^0$ and $\bar\Lambda_b^0$ candidates that are reconstructed in 4.9 fb$^{-1}$ of ATLAS data c...
