Prospects of CKM parameter measurements at Belle II [PDF]

Proceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2017), 2018
Semileptonic and leptonic $B$ decays are powerful probes to search for physics beyond the Standard Model (SM) as they can be calculated in the SM with high precision. We report recent results on rare $B$ decays with leptons from the Belle experiment at the KEKB $e^+e^−$ collider.

Constraining the CKM parameters usingCPviolation in semileptonicBdecays [PDF]

Physical Review D, 1999
We discuss the usefulness of the CP violating semi-leptonic asymmetry a_{SL} not only as a signal of new physics, but also as a tool in constraining the CKM parameters. We show that this technique could yield useful results in the first years of running at the B factories.

Extractions of |V ub |/|V cb | from a combined study of the exclusive b → u c ℓ − ν ¯ ℓ $$ b\to u(c){\ell}^{-}{\overline{\nu}}_{\ell } $$ decays

Journal of High Energy Physics, 2023
We have extracted the ratio |V ub |/|V cb | from a combined study of the available inputs on B ¯ → π ρ ω ℓ − ν ¯ ℓ $$ \overline{B}\to \left(\pi, \rho, \omega \right){\ell}^{-}{\overline{\nu}}_{\ell } $$ and B ¯ B ¯ s → D ∗ D s ∗ ℓ − ν ¯ ℓ ℓ = μ or e ...

Quaternionic Electroweak Theory and CKM Matrix [PDF]

, 1997
We find in our quaternionic version of the electroweak theory an apparently hopeless problem: In going from complex to quaternions, the calculation of the real-valued parameters of the CKM matrix drastically changes.

A Determination of the CKM Parameter |Vus|

, 2004
We present a determination of the CKM parameter |Vus| based on new measurements of the six largest KL branching fractions and semileptonic form factors by the KTeV (E832) experiment at Fermilab. We find |Vus| = 0.2252 +- 0.0008(KTeV) +- 0.0021(ext), where the errors are from KTeV measurements and from external sources.

Unveiling the Link between the Third Law of Comminution and the Grinding Kinetics Behaviour of Several Ores

Metals, 2021
As a continuation of a previous research work carried out to estimate the Bond work index (wi) by using a simulator based on the cumulative kinetic model (CKM), a deeper analysis was carried out to determine the link between the kinetic and energy ...

Parametrization of PMNS matrix based on dodeca-symmetry

, 2011
The dodeca symmetry is designed to obtain the Cabibbo angle $\theta_C^{\rm CKM}$ approximately $15^{\rm o}$ and the (11) element of $\Vp$ as $\cos 30^{\rm o}$, leading to $\theta_1^{\rm PMNS}+\theta_C^{\rm CKM}\simeq 45^{\rm o}$.

Interfacial Polysulfide Confinement via Spatially Controlled Sulfonated Metal–Organic Polyhedra Coatings in Lithium–Sulfur Batteries

Advanced Science, EarlyView.
Spatially controlled sulfonated metal–organic polyhedra (SMOP) coating on sulfur‐loaded hollow carbon spheres form ultrathin, conformal interfacial barriers that selectively confine soluble polysulfides, stabilize sulfur redox, and suppress shuttle reactions.
