Asymmetries and observables for $\Lambda_b\rightarrow \Lambda \ell^+\ell^-$

TL;DR

This paper proposes new angular observables and asymmetries in the semi-leptonic decay $oldsymbol{ ext{Lambda}_b o ext{Lambda} ext{l}^+ ext{l}^-}$ to test for potential new physics beyond the standard model.

Contribution

It introduces novel angular observables and asymmetries specifically designed for the $ ext{Lambda}_b o ext{Lambda} ext{l}^+ ext{l}^-$ decay process.

Findings

New observables can distinguish between standard model and new physics scenarios.

Asymmetries provide sensitive tests for physics beyond the standard model.

The proposed observables can be measured in current or future experiments.

Abstract

The semi-leptonic baryonic $b\to s$ decay, $\Lambda_b\rightarrow \Lambda \ell^+\ell^-$, has been studied and new angular observables and asymmetries have been proposed which can test the presence of new physics beyond the standard model.
