Light quark loops in K ± → π ± ν ν ¯ $$ {K}^{\pm}\to {\pi}^{\pm}\nu \overline{\nu} $$ from vector meson dominance and update on the Kaon Unitarity Triangle

Journal of High Energy Physics
We use vector meson dominance to calculate non-perturbative contributions to the branching ratio of the rare decay K ± → π ± ν ν ¯ $$ {K}^{\pm}\to {\pi}^{\pm}\nu \overline{\nu} $$ stemming from matrix elements involving up-quark loops.

Unitarity triangle angles explained: a predictive new quark mass matrix texture

Journal of High Energy Physics
We propose a novel quark mass matrix texture-pair with five free parameters, which fits the four quark mass ratios m s /m b , m d /m b , m c /m t , m u /m t , and the four CKM quark mixing observables.

Precision measurement of the CKM parameter sin(𝟮𝝱) with the LHCb experiment

, 2015
Die vorliegende Dissertation beschreibt eine zerfallszeitabhängige Messung von CP-Verletzung im Zerfall von B0- und Anti-B0-Mesonen in ihren gemeinsamen Endzustand J/ψ KS. Die Größe der Symmetrieverletzung in der Interferenz der Zerfalls- und Mischungs-Amplituden der B-Mesonen lässt sich durch die CP-Observablen S(J/ψ KS) und C(J/ψ KS) ausdrücken und ...

Radiative corrections to superallowed beta decays at O α 2 Z $$ \mathcal{O}\left({\alpha}^2Z\right) $$

Journal of High Energy Physics
We compute O α 2 Z $$ \mathcal{O}\left({\alpha}^2Z\right) $$ radiative corrections to superallowed β decays with a heavy-particle effective field theory that systematically describes the interactions of low-energy ultrasoft photons with nuclei.

Global analysis of charm mixing parameters and determination of the CKM angle gamma γ

Physical Review D
We present an updated global analysis of beauty decays sensitive to the angle γ of the Cabibbo-Kobayashi-Maskawa matrix and of D-meson mixing data in the framework of approximate universality, in which CP violation in D−D¯ mixing is described in terms of two universal weak phases corresponding to dispersive and absorptive contributions.

Sp(6, Z) modular symmetry in flavor structures: quark flavor models and Siegel modular forms for $$\widetilde{\Delta }\left(96\right)$$

Journal of High Energy Physics
We study an approach to construct Siegel modular forms from Sp(6, Z). Zero-mode wave functions on T 6 with magnetic flux background behave Siegel modular forms at the origin.

Association between the triglyceride-glucose-waist-to-height ratio and early arterial stiffness in cardiovascular-kidney-metabolic syndrome

European Journal of Medical Research
Objective To explore the relationship between the triglyceride-glucose-waist-to-height ratio (TyG-WHtR) and brachial-ankle pulse wave velocity (baPWV), and to evaluate its utility as an early indicator of arterial stiffness in individuals with ...
