Light cone QCD sum rules study of the semileptonic heavy Xi_(Q) and Xi'_(Q) transitions to Xi and Sigma baryons
read the original abstract
The semileptonic decays of heavy spin--1/2, $\Xi_{b(c)}$ and $\Xi'_{b(c)}$ baryons to the light spin-- 1/2, $\Xi$ and $\Sigma $ baryons are investigated in the framework of the light cone QCD sum rules. In particular, using the most general form of the interpolating currents for the heavy baryons as well as the distribution amplitudes of the $\Xi$ and $\Sigma $ baryons, we calculate all form factors entering the matrix elements of the corresponding effective Hamiltonians in full QCD. Having calculated the responsible form factors, we evaluate the decay rates and branching fractions of the related transitions.

Semileptonic neutral current decays of $\Xi_b$ with dileptons or dineutrinos in the final state
Perturbative QCD calculations find that branching fractions for Ξ_b to Ξ lepton-pair decays lie within LHCb reach and that angular observables plus a specific ratio can constrain Wilson coefficients and extract |V_td/...

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.
