$b\to s\gamma$ decays in the Left-Right Symmetric Model

Abstract

We consider $b\to s\gamma$ decays in the Left-Right Symmetric Model. Values of observables sensitive to chiral structure such as the $\Lambda$ polarization in the ${\Lambda }_b\to \Lambda \gamma$ decays and the mixing-induced CP asymmetries in the $B_{d,s}\to M^0\gamma$ decays can deviate in the LRSM significantly from the SM values. The combined analysis of $P_{\Lambda }$ and $A_{CP}$ as well as $\mathcal{B}\mathcal{R}(b\to s\gamma )$ can be used to determine the model parameters.
