Combining Pati-Salam and Flavour Symmetries

, 2015
We construct an extension of the Standard Model (SM) which is based on grand unification with Pati-Salam symmetry. The setup is supplemented with the idea of spontaneous flavour symmetry breaking which is mediated through flavon fields with ...

Visible GeV ALP from TeV Vector‐Like Leptons

Fortschritte der Physik, Volume 73, Issue 3, March 2025.
Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Flavor and CP Violation Induced by Atmospheric Neutrino Mixing

, 2004
Neutrino oscillation experiments suggest existence of new flavor-violating interactions in high energy scale. It may be possible to probe them by the flavor- and CP-violating processes in leptons and hadrons in the supersymmetric (SUSY) models.

Studies of Parity Violation in Atoms

Annalen der Physik, Volume 537, Issue 2, February 2025.
This article provides an overview of atomic parity violation (APV), emphasizing its role in testing the Standard Model and probing new physics. The review discusses manifestations of APV, including nuclear‐spin‐independent and dependent effects, and explores isotopic comparison as a method for precision measurements.

R K * $$ {R}_{K^{\left(*\right)}} $$ with leptoquarks and the origin of Yukawa couplings

Journal of High Energy Physics, 2018
We construct a model where the Yukawa couplings of the Standard Model (SM) fermions arise from the breaking of a Z 2 symmetry and through mixing with a fourth family of vector-like fermions.

Muon to electron conversion in the Littlest Higgs model with T-parity

, 2010
Little Higgs models provide a natural explanation of the little hierarchy between the electroweak scale and a few TeV scale, where new physics is expected.

Interplay Between MW, ΩCDMh2, and (g − 2)μ in Flavor Symmetry–Based Supersymmetric Models

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
We study the phenomenological implications of the minimal supersymmetric standard model (MSSM) augmented by a nonabelian flavor symmetry labeled as sMSSM. Incorporating this flavor symmetry allows for a significant reduction in the original plethora of free parameters present in the MSSM, ultimately reducing them down to just seven in sMSSM.

Flavor structure from misalignment of inner products in noncommutative geometry

Journal of High Energy Physics, 2018
In this letter, we consider an idea that induces flavor structure from inner products in noncommutative geometry. Assuming proper components of vectors v (L,R)i in enlarged representation space for fermions, we can induce the waterfall texture for Yukawa

Renormalization Invariants and Quark Flavor Mixings

, 2010
A set of renormalization invariants is constructed using approximate, two-flavor, analytic solutions for RGEs. These invariants exhibit explicitly the correlation between quark flavor mixings and mass ratios in the context of the SM, DHM and MSSM of ...

Biogenic Amines in Cheese: Health Risks, Regulatory Perspectives, and Analytical Advances

Journal of Food Processing and Preservation, Volume 2025, Issue 1, 2025.
Biogenic amines (BAs) are nitrogenous compounds formed by microbial decarboxylation of amino acids in various foods, particularly fermented, aged, or improperly stored products. While some BAs play physiological roles, excessive intake can lead to toxic effects.
