The Omega_b* -> Omega_c* l nu semileptonic decay widths are predicted with QCD sum rules: about 2.5e-12 GeV for electron/muon channels and 0.71e-12 GeV for the tau channel, with R = 0.29.

abstract
In this article, we study the ${3\over 2}^+$ heavy and doubly heavy baryon states $\Xi^*_{cc}$, $\Omega^*_{cc}$, $\Xi^*_{bb}$, $\Omega^*_{bb}$, $\Sigma_c^*$, $\Xi_c^*$, $\Omega_c^*$, $\Sigma_b^*$, $\Xi_b^*$ and $\Omega_b^*$ by subtracting the contributions from the corresponding ${3\over 2}^-$ heavy and doubly heavy baryon states with the QCD sum rules, and make reasonable predictions for their masses.

Semileptonic $\Omega_{b}^{*}\rightarrow\Omega_{c}^{*} \ell \bar{\nu}_{\ell}$ transition in QCD
The Omega_b* -> Omega_c* l nu semileptonic decay widths are predicted with QCD sum rules: about 2.5e-12 GeV for electron/muon channels and 0.71e-12 GeV for the tau channel, with R = 0.29.
