Inequalities for Standard Model Yukawa couplings

Journal of High Energy Physics
We show that the Standard Model Yukawa matrices satisfy a set of simple yet nontrivial inequalities. The relations we derive are independent of the basis used to define the fermion fields, and, amongst other things, place strong constraints on the ...

CP violation of quarks in A4 modular invariance

Physics Letters B, 2019
We discuss the quark mass matrices in the A4 modular symmetry, where the A4 triplet of Higgs is introduced for each up-quark and down-quark sectors, respectively.

Operating in perpetual motion? Coping with the dark side of global boundary spanning

Global Strategy Journal, EarlyView.
Abstract Research Summary This paper explores how individuals experience and cope with the demands of global boundary spanning in multinational enterprises (MNEs). We foreground temporary colocation as a modality through which mobile global boundary spanners repeatedly traverse multiple boundaries, triggering intense demands with adverse consequences ...

Determination of B-meson distribution amplitudes from B → π, K, D transition form factors

Journal of High Energy Physics
Recent work on B → π, K and B → D form factors from lattice QCD and light-cone sum rules has made it possible to constrain the inverse moment λ B of the B-meson light-cone distribution amplitudes by performing a global fit of B → π, K, D form factors. We

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 ...

Stage‐Dependent Prognostic Value of the Joint MASLD–NAFLD Fibrosis Score Phenotype Across the Cardiovascular–Kidney–Metabolic Syndrome Continuum: A Retrospective NHANES Cohort Analysis, 1999–2018

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The cardiovascular–kidney–metabolic (CKM) framework and metabolic dysfunction–associated steatotic liver disease (MASLD) describe a shared clinical continuum, but the prognostic value of joint fatty liver index (FLI)–NAFLD fibrosis score (NFS) phenotypes across CKM stages is uncertain.

First look at CKM parameters from early Belle II data [PDF]

Proceedings of European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2019), 2020
After its commissioning in 2018, the Belle II experiment has started registering first physics data delivered by SuperKEKB in 2019. The Belle II physics program focuses on the search for physics beyond the standard model with precise measurements in the flavour sector. The huge targeted dataset and the B-factory particular collision scheme will help to

331 model predictions for rare B and K decays, and ∆F = 2 processes: an update

Journal of High Energy Physics, 2023
Motivated by the improved results from the HPQCD lattice collaboration on the hadronic matrix elements entering ∆M s,d in B s , d 0 − B ¯ s , d 0 $$ {B}_{s,d}^0-{\overline{B}}_{s,d}^0 $$ mixings and the increase of the experimental branching ratio for B ...

Development and Characterization of Liposomes Containing a Zn(II) Porphyrin Derivative for the Application of Photodynamic Therapy in the Treatment of Breast Cancer

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives This study aims to synthesize and characterize lipid nanosystems (liposomes) for the incorporation of a Zn(II) porphyrin derivative, Zn(II) meso‐tetrakis(N‐n‐hexylpyridinium‐2‐yl)porphyrin (ZnTnHex‐2‐PyP4+, ZnPH), intending to employ an alternative method of treatment, such as photodynamic therapy (PDT), for breast cancer (BC ...

Simultaneous determination of CKM angle $\gamma$ and charm mixing parameters

, 2021
A combination of measurements sensitive to the $CP$ violation angle $\gamma$ of the Cabibbo--Kobayashi--Maskawa (CKM) unitarity triangle and to the charm mixing parameters that describe oscillations between $D^0$ and $\overline{D}^0$ mesons is performed.
