Semileptonic transition of Sigma_(b) to Sigma in Light Cone QCD Sum Rules
read the original abstract
We use distribution amplitudes of the light $\Sigma$ baryon and the most general form of the interpolating current for heavy $\Sigma_b$ baryon to investigate the semileptonic $\Sigma_b\rightarrow \Sigma l^+l^-$ transition in light cone QCD sum rules. We calculate all twelve form factors responsible for this transition and use them to evaluate the branching ratio of the considered channel. The order of branching fraction shows that this channel can be detected at LHC.

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 the 2HDM
Rare bottom-baryon dileptonic decays are analyzed in the Type III 2HDM using light-cone QCD form factors, with predictions for branching ratios and asymmetries testable at LHCb and Belle II.

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 the 2HDM
Rare Λ_b, Σ_b and Ξ_b dileptonic decays are analyzed in Type-III 2HDM; branching ratios and lepton asymmetries may deviate from the SM and be probeable at LHCb/Belle II.

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 the 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.
