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…
Gravitational wave signatures of magnetized Ernst black hole
Fazlay Ahmed, Sanjar Shaymatov, Chengxun Yuan +1
We investigate gravitational wave (GW) emission from periodic timelike orbits of a test particle around a magnetized Ernst black hole and the gravitational waveforms generated by t…
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…
Dark-Portal Leptogenesis in a Non-Holomorphic Modular Scoto-Seesaw Model
Salah Nasri, Labh Singh, Tapender +1
This work explores the neutrino phenomenology of the scotoseesaw model under non-holomorphic modular flavor symmetry providing a non-SUSY framework for realization of the mod…
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…
