Analysis of the semileptonic decays $\Sigma_b\to\Sigma_cl\bar{\nu}_l$, $\Xi'_b\to\Xi'_cl\bar{\nu}_l$ and $\Omega_b\to\Omega_cl\bar{\nu}_l$ in QCD sum rules

Bin Wu, Dian-Yong Chen, Guo-Liang Yu, Jie Lu, Zhi-Gang Wang

Three-point QCD sum rules calculations indicate that the semileptonic decay widths for Σ_b→Σ_c, Ξ'_b→Ξ'_c and Ω_b→Ω_c approximately satisfy SU(3) flavor symmetry.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The results indicate that these decay widths approximately satisfy SU(3) flavor symmetry. Next, we calculate the branching ratios for the decay process Ω_b→Ω_c l ν̄_l and compare them with the results from other collaborations.

C2weakest assumption

The systematic inclusion of higher-dimensional terms accounts for a broader set of Feynman diagrams, thereby enhancing the comprehensiveness and reliability of the operator product expansion.

C3one line summary

Electroweak form factors for Σ_b→Σ_c, Ξ'_b→Ξ'_c and Ω_b→Ω_c transitions are computed in QCD sum rules, producing decay widths that approximately obey SU(3) flavor symmetry along with branching ratios and new-physics probes for the Ω_b channel.
