Properties of $b$-hadrons with ATLAS: $B^0_s$ rare decays and $\Lambda_b$ decay properties.

Measurements of the properties of $b$-hadrons are presented based on 5.25~$fb^{-1}$ of $pp$\ncollision data recorded by the ATLAS experiment during 2011 LHC operation. \nWe present an updated limit on the the $B_s\rightarrow\mu^+\mu^-$ branching ratio, a determination of the the $\Lambda^0_b$ mass a...

description Measurements of the properties of $b$-hadrons are presented based on 5.25~$fb^{-1}$ of $pp$\ncollision data recorded by the ATLAS experiment during 2011 LHC operation. \nWe present an updated limit on the the $B_s\rightarrow\mu^+\mu^-$ branching ratio, a determination of the the $\Lambda^0_b$ mass and lifetime and a new measurement of the parity violation asymmetry parameter $\alpha_b$ and helicity amplitudes of the decay of the $\Lambda^0_b\rightarrow{J/\psi}(\mu^+\mu^-)\Lambda^0(p^+\pi^-)$.
