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.

Rest-activity rhythms and cardiovascular events in cardiovascular–kidney–metabolic syndrome: evidence from two nationwide cohorts

open access: yesAmerican Journal of Preventive Cardiology
Background: Circadian rest–activity rhythm (CRAR) is a modifiable determinant of metabolic and cardiovascular health, yet its role in cardiovascular events and mortality among individuals with cardiovascular–kidney–metabolic (CKM) syndrome remains ...

Implication of the $B$ $\rightarrow$ ($\rho$, $\omega$) $\gamma$ branching ratios for the CKM phenomenology

open access: yes, 2004
We study the implication of the recent measurement by the BELLE Collaboration of the averaged branching fraction B̄exp[B→(ρ,ω)γ]=(1.8+0.6−0.5±0.1)×10−6 for the CKM phenomenology. Combined with the averaged branching fraction B̄exp(B→K∗γ)=(4.06±0.26)×10−5

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 $

WG V conveners' report: Charm inputs for CKM physics

open access: yes, 2003
We introduce the contributions to the proceedings of Working Group V. The main topics were: present and future experiments dedicated to charm physics, the interplay between high-precision measurements and better control over theoretical uncertainties ...

SLAC-PUB-15659 CKM angles and sides from BABAR

open access: yes, 2014
on behalf of the BABAR Collaboration Abstract. The CKM paradigm has been proven to be successful in explaining the flavour structure of the standard model and the non-trivial imaginary phase of the CKM matrix is the only know source of CP-violation.

Exploiting perpendicular momentum distributions of semileptonic decays: B ¯ s 0 → D s + μ − ν ¯ $$ {\overline{B}}_s^0\to {D}_s^{+}{\mu}^{-}\overline{\nu} $$ as a case study

open access: yesJournal of High Energy Physics
We derive the differential distribution of semileptonic decays with respect to the perpendicular momentum component of the final state hadron. The benefits and shortfalls arising from measurements of these distributions are discussed.

Relationships between Quark Masses and the CKM Elements

open access: yes, 1997
There are mysteries that the origin of small values in the Cabibbo-KobayashiMaskawa (CKM) matrix and the reason why the CKM matrix is close the unit matrix. We use the general quark mass matrices in order to solve the these problems.
