Abstract
An 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.
