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

Abstract

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 density-matrices are derived to perform tests of both Time-Reversal (TR) and CP violation.
