dc.description.abstractAn angular analysis of Λ0 b → J /ψΛ decays is performed using a data sample corresponding to 1.0 fb−1 collected in pp collisions at √s = 7 TeV with the LHCb detector at the LHC. A parity violating asymmetry parameter characterising the Λ0 b → J /ψΛ decay of 0.05 ± 0.17 ± 0.07 and a Λ0 b transverse production polarisation of 0.06 ± 0.07 ± 0.02 are measured, where the first uncertainty is statistical and the second systematic
