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

open access: yesJournal 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 |.

Worries and Hopes for SUSY in CKM Physics: The b to s Example

open access: yes, 2003
We discuss the twofold role of flavor and CP violation as a constraint in model building and as a signal of SUSY. Considering as an example b to s transitions, we analyze present bounds on SUSY parameters, discuss possible deviations from SM predictions ...

HFAG-charm averages

open access: yes, 2014
The extraction of charm mixing and CP violation parameters requires the combination of many measurements. The latest averages are reviewed and the contribution of individual measurements is discussed.

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

open access: yesJournal 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

open access: yesJournal 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 $

A model independent determination of the B -> Xs gamma decay rate

open access: yes, 2013
The goal of the SIMBA collaboration is to provide a global fit to the available measurements of inclusive B -> X_s gamma and B -> X_u l nu decays. By performing a global fit one is able to simultaneously determine the relevant normalizations, i.e.

Improved strong coupling determinations from hadronic decays of electroweak bosons at N$^3$LO accuracy

open access: yes, 2020
We present two new extractions of the QCD coupling constant at the Z pole, $\alpha_S(m_Z)$, from detailed comparisons of inclusive W and Z hadronic decays data to state-of-the-art perturbative Quantum Chromodynamics calculations at next-to-next-to-next ...
