Quark mixing renormalization effects in the determination of the CKM parameters |V_{ij}|

, 2008
We briefly review existing proposals for the renormalization of the Cabibbo-Kobayashi-Maskawa (CKM) matrix and study the numerical effects of several of them on the W-boson hadronic partial decay widths. We then use these results to evaluate the relative shifts on the CKM parameters |V_{ij}|^2 induced by the quark mixing renormalization effects, as ...

Constraints on a generalization of geometric quantum mechanics from neutrino and B 0- B 0 ¯ $$ \overline{B^0} $$ oscillations

Journal of High Energy Physics
Nambu Quantum Mechanics, proposed in Phys. Lett. B536, 305 (2002), is a deformation of canonical Quantum Mechanics in which the manifold over which the “phase” of an energy eigenstate time evolves is modified.

An Algebraic Zero-Parameter Derivation of the CKM Matrix

Abstract:  Starting from the SU(2) algebraic structure of the imaginary quaternion space, this paper presents a zero-parameter algebraic derivation of all four independent parameters of the CKM matrix—the three mixing angles θ₁₂, θ₂₃, θ₁₃ and the CP-violating phase δ. The core mechanism is wedge product conservation: the exterior algebra area element |

Association of cumulative exposure and dynamic trajectories of the C-reactive protein-triglyceride-glucose and its modified indices with cardiovascular disease in individuals with cardiovascular-kidney-metabolic syndrome stages 0–3: a longitudinal analysis based on CHARLS

Cardiovascular Diabetology
Background To evaluate the incremental predictive value of modifying the C-reactive protein-triglyceride-glucose (CTI) index with obesity parameters for incident cardiovascular disease (CVD) across Cardiovascular-Kidney-Metabolic (CKM) syndrome stages ...

The q 2 moments in inclusive semileptonic B decays

Journal of High Energy Physics
We compute the first moments of the q 2 distribution in inclusive semileptonic B decays as functions of the lower cut on q 2, confirming a number of results given in the literature and adding the O α s 2 β 0 $$ O\left({\alpha}_s^2{\beta}_0\right) $$ BLM ...

A meta-analysis of the association of CKM gene rs8111989 polymorphism with sport performance

, 2017
The muscle-specific creatine kinase (CKM) A/G variants (rs8111989) have been associated with skeletal muscle performance in humans; they are correlated with physical performance and contribute to differences in the maximum oxygen uptake (VO2max ...

Precision Measurements of the CKM Parameters (Mainly $$\gamma /\phi _{3}$$ Measurements) [PDF]

, 2019
The CKM angle \(\gamma /\phi _{3}\) is the only one that is accessible with tree level decays in a theoretically clean way such that it provides a precision test of CP violation in the standard model. The Belle II experiment is a substantial upgrade of the Belle detector and will operate at the SuperKEKB asymmetric-energy \(e^{+}e^{-}\) collider.

Quark-hadron duality violations and higher-order 1/m b corrections in inclusive semileptonic B decays

Journal of High Energy Physics
The theoretical description and data for inclusive semileptonic B decays have reached incredible precision. This motivated us to re-animate the discussion of possible Quark-Hadron Duality violations.
