Measurements of the $\Lambda_b^0 \to J/\psi \Lambda$ decay amplitudes and the $\Lambda_b^0$ polarisation in $pp$ collisions at $\sqrt{s} = 7$ TeV

An angular analysis of $\Lambda_b^0 \to J/\psi \Lambda$ decays is performed using a data sample corresponding to $1.0$ ${\rm fb}^{-1}$ collected in $pp$ collisions at $\sqrt{s} = 7$ TeV with the LHCb detector at the LHC. A parity violating asymmetry parameter characterising the $\Lambda_b^0 \to J/\p...
