Z'-Mediated Slepton and Sneutrino Signatures at HL-LHC
Kareem Ezzat, Nidal Chamoun, Shaaban Khalil
We investigate the discovery potential of a heavy boson as a portal to charged sleptons and right-handed sneutrinos within the Supersymmetric Standard Model (BLSSM) at t…
A Comparative Study of Correlation and Relativistic Effects on Atomic Ionization Energy
Mohamed Kahil, Fatima Fakih, Nabil Joudieh +1
This study investigates the interplay between relativistic effects and electron correlation effects on the first ionization energies of heavy atoms (Au through Rn, Z = 79-86). We p…
Constraining nonminimal f(T) gravity from Primordial Nucleosynthesis to Late-Universe observations
Yahia Al-Omar, Majida Nahili, Nidal Chamoun
We present a multi-epoch test of f(T) gravity with nonminimal torsion-matter coupling, combining early- and late-Universe observations. At the MeV scale, Big-Bang Nucleosynthesis c…
Cosmological Constraints on f(T,B) Gravity from Observations of Early and Late Universe
Yahia Al-Omar, Majida Nahili, Nidal Chamoun
We present a unified framework that combines early- and late-Universe observations to constrain three functional realizations of f(T,B) gravity: the linear, quadratic, and general…
Cosmological Constraints on Gravity from Observations of Early and Late Universe
Yahia Al-Omar, Majida Nahili, Nidal Chamoun +1
This study proposes a unified framework comprising two complementary approaches to constrain three functional forms of gravity, namely the linear, quadratic, and general p…
Quantum Study of Dispersion-Corrected Electronic and Optical Properties of syn- and anti- B18H22 Clusters with/without Sulfur Doping for Tunable Optoelectronics
Fakher Abbas, Nabil Joudieh, Habib Abboud +1
This study presents a detailed quantum chemical investigation of the electronic and excited-state properties of syn- and anti-isomers of the borane cluster B18H22 and their sulfur-…
