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