Comprehensive analyses of rare $ \Lambda_b \rightarrow \Lambda \ell^+ \ell^-$, $\Sigma_b \rightarrow \Sigma \ell^+ \ell^-$ and $\Xi_b \rightarrow \Xi \ell^+ \ell^-$ decays in 2HDM
The work computes differential and total branching ratios plus forward-backward asymmetries for Λ_b → Λ ℓ⁺ℓ⁻, Σ_b → Σ ℓ⁺ℓ⁻ and Ξ_b → Ξ ℓ⁺ℓ⁻ in 2HDM Type III and contrasts them with SM predictions.

We aim to assess the impact of the Two-Higgs-Doublet Model with Type III on various observables, such as the differential branching ratio, total branching ratio, and lepton forward-backward asymmetries using the decay amplitude and the transition matrix elements in terms of form factors calculated via light cone QCD in full theory.
The transition matrix elements are expressed in terms of form factors calculated via light-cone QCD sum rules in full theory; any systematic uncertainty or model dependence in those form factors directly propagates into the predicted observables.
