An angular distribution analysis of ${\Lambda }_b$ decays

O. Leitner, Z. J. Ajaltouni, E. Conte

A study of the angular distributions of the processes ${\Lambda }_b\to \Lambda V(1^{-})$ with $V({J/\Psi ,\rho }^0)$ is performed. Emphasis is put on the initial ${\Lambda }_b$ polarization and the polarization d…
