Study of the $\Lambda^{0}_{b}$ decay properties with the ATLAS experiment

The ATLAS detector at the LHC is collecting - among others - a large statistics of $\Lambda^{0}_{b}$ decays, allowing the study of production and decay properties of this $b$-flavored hadron. This statistics is what allowed one of the most precise measurements of the $\Lambda^{0}_b$ lifetime. We will review ATLAS’ latest results on the decay properties of this baryon, including the measurement of the parity violating asymmetry parameter $\alpha_{b}$ in $\Lambda^{0}_{b}\rightarrow$J/$\psi\Lambda^{0}$, obtained from the study of angular correlations in the $\mu^{+}$$\mu^{-}$ $p$$\pi^{-}$ final state. The measurement is compared to predictions based on perturbative QCD and heavy quarks effective theory.
