Measurement of helicity amplitudes of the decay $\Lambda_b^0 \to J/\psi +\Lambda^0$ in the ATLAS experiment
A measurement of the helicity amplitudes and the parity violating decay asymmetry parameter, $\alpha_b$ for the $\Lambda_b^0$ hyperon decay $\Lambda_b^0\to J/\psi\Lambda^0$ is reported. The analysis is based on about 1400 $\Lambda_b^0$ and $\bar{\Lambda}_b^0$ baryons selected in 4.6 fb$^{-1}$ of pro...
