TL;DR

This paper investigates how the Left-Right Symmetric Model affects $b o s \gamma$ decays, highlighting potential deviations in observables like polarization and CP asymmetries from Standard Model predictions.

Contribution

It provides a combined analysis framework for observables to constrain parameters of the Left-Right Symmetric Model based on $b o s \gamma$ decay data.

Findings

Significant deviations in polarization and CP asymmetries from SM predictions.

Combined analysis can effectively constrain LRSM parameters.

Potential for new physics signals in $b o s \gamma$ decay observables.

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 ${\cal BR}(b \to s \gamma)$ can be used to determine the model parameters.
