Complete O α s 2 $$ \mathcal{O}\left({\alpha}_s^2\right) $$ corrections to the leptonic invariant mass spectrum in b → X c l ν ¯ l $$ b\to {X}_cl{\overline{\nu}}_l $$ decay

Journal of High Energy Physics
In the determination of the Cabibbo-Kobayashi-Maskawa matrix element |V cb | from inclusive semileptonic B-meson decays, moments of the leptonic invariant mass spectrum constitute valuable observables.

Inclusive semileptonic B s 0 $$ {B}_s^0 $$ meson decays at the LHC via a sum-of-exclusive modes technique: possibilities and prospects

Journal of High Energy Physics
We propose an approach for measuring the moments of the hadronic invariant mass distribution in semileptonic B s 0 $$ {B}_s^0 $$ meson decays using a sum-of-exclusive technique. Using the present and foreseen knowledge about exclusive semileptonic B s 0 $

$\Omega_b$ semi-leptonic weak decays

, 2011
$\Omega_b \rightarrow \Omega_c^{(*)}$ semi-leptonic decays are studied in details. Relevant helicity amplitudes are written down. Both unpolarized and polarized $\Omega_b$ cases are considered. Decay angular distributions, asymmetry parameters and semileptonic decay rates are calculated, with numerical results using leading order results of the large ...

New physics searches via angular distributions of B ¯ → D ∗ → Dπ τ → ℓ ν τ ν ¯ ℓ ν ¯ τ $$ \overline{B}\to {D}^{\ast}\left(\to D\pi \right)\tau \left(\to \ell {\nu}_{\tau }{\overline{\nu}}_{\ell}\right){\overline{\nu}}_{\tau } $$ decays

Journal of High Energy Physics
The study of B ¯ → D ∗ τ ν ¯ τ $$ \overline{B}\to {D}^{\ast}\tau {\overline{\nu}}_{\tau } $$ angular distribution can be used to obtain information about new physics (or beyond the Standard Model) couplings, which are motivated by various B anomalies ...

Inclusive semileptonic b → c ℓ ν ¯ $$ b\to c\ell \overline{\nu} $$ decays to order 1 / m b 5 $$ 1/{m}_b^5 $$

Journal of High Energy Physics
Inclusive semileptonic B → X c ℓ ν ¯ $$ B\to {X}_c\ell \overline{\nu} $$ decays can be described in the Heavy Quark Expansion (HQE) and allow for a precision determination of the CKM element |V cb |.
