Flavor structures of quarks and leptons from flipped SU(5) GUT with A 4 modular flavor symmetry
Journal of High Energy Physics, 2023 We propose to generate the flavor structures of the Standard Model plus neutrinos from flipped SU(5) GUT with A 4 modular flavor symmetry. Possible way to assign different moduli values for quarks and leptons in modular GUT scheme is discussed.

Flavourful SMEFT likelihood for Higgs and electroweak data
Journal of High Energy Physics, 2020 We perform an updated fit to LHC Higgs data and LEP electroweak precision tests in the framework of the Standard Model Effective Field Theory (SMEFT). We assume a generic structure of the SMEFT operators without imposing any flavour symmetries.

The interplay between grand unified and flavour symmetries in a Pati-Salam × S4 model [PDF]
, 2010 Both discrete flavour symmetries and Grand Unified symmetries explain apparent structures in the mass sector of the Standard Model. A model that combines both symmetries is therefore very appealing.

Insights into grand unified theories from current experimental data [PDF]
, 2015 In this thesis, we investigate several ways how the structure of a high energy particle physics model constituting a grand unification theory (GUT) in supersymmetry (SUSY) can be inferred from multiple types of information obtained at low energy ...

Finite family groups for fermionic and leptoquark mixing patterns
Journal of High Energy Physics, 2020 We employ a bottom-up and model-independent technique to search for non-Abelian discrete flavour symmetries capable of predicting viable CKM and PMNS matrices alongside of special patterns of leptoquark couplings.

Leading directions in the SMEFT
Journal of High Energy Physics, 2023 Short-distance new physics at (or slightly) above the TeV scale should not excessively violate the approximate flavor symmetries of the SM in order to comply with stringent constraints from flavor-changing neutral currents.

Neutrino masses and flavour symmetry [PDF]
Il Nuovo Cimento A, 1997 The problem of neutrino masses and mixing angles is analysed in a class of supersymmetric grand unified models, withSO(10) gauge symmetry and globalU(2) flavour symmetry. Adopting the seesaw mechanism for the generation of the neutrino masses, one obtains a mass matrix for the left-handed neutrinos which is directly related to the parameters of the ...

The Interplay Between GUT and Flavour Symmetries in a Pati-Salam x S4 Model [PDF]
, 2010 Both Grand Unified symmetries and discrete flavour symmetries are appealing ways to describe apparent structures in the gauge and flavour sectors of the Standard Model. Both symmetries put constraints on the high energy behaviour of the theory.

Advanced Engineering Materials, EarlyView.This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...
