A Novel One-loop Model for Majorana Neutrino Mass and Dark Matter
Mohamed Belfkir, Mohamed Amin Loualidi, Salah Nasri
We present the first complete field-theoretic realization of the finite one-loop T4-3-i topology for Majorana neutrino mass. Here, T4-3-i denotes a one-loop realization of the Wein…
Radiative Neutrino Mass in a Nonholomorphic Modular Invariant Model
Mohamed Amin Loualidi, Mohamed Miskaoui, Salah Nasri
The T4-2-i topology provides a one-loop realization of Majorana neutrino mass and may be viewed as a radiative extension of the type-II seesaw, with a scalar triplet, two inert sca…
Radiative neutrino mass generation and dark matter through vectorlike leptons
Mohamed Amin Loualidi, Salah Nasri, Maximiliano A. Rivera
This study presents a radiative three-loop model for neutrino mass generation, employing an asymmetric Yukawa coupling between two new scalar doublets and vectorlike lept…
Boosting Sensitivity to with Graph Neural Networks and XGBoost
Mohamed Belfkir, Mohamed Amin Loualidi, Salah Nasri
In this paper, we explore the use of advanced machine learning (ML) techniques to enhance the sensitivity of double Higgs boson searches in the \( HH \to b\bar{b}γγ\) decay chann…
Nonholomorphic modular invariance for fermion masses and mixing in SU(5) GUT
Mohamed Amin Loualidi, Mohamed Miskaoui, Salah Nasri
Addressing the fermion flavor structures using modular invariance is a challenging task in the framework of quark-lepton unification. Building on recent applications of modular sym…
Fermion Masses and Mixing in Pati-Salam Unification with Modular Symmetry
Mohamed Belfkir, Mohamed Amin Loualidi, Salah Nasri
Modular invariance has recently paved new promising directions in flavor model building. Motivated by this development, we present in this work the first implementation of the $S_3…
