Axion from Quivers in Type II Superstrings
Adil Belhaj, Salah Eddine Ennadifi, Maria Pilar Garcia del Moral
We investigate a string-inspired axion extension of the standard model obtained from Type II superstrings using quiver method. In the first part, we discuss intersecting Type IIA D…
Exotic Hadrons and Underlying Z_{2,3} Symmetries
Adil Belhaj, Salah Eddine Ennadifi, Moulay Brahim Sedra
The recent observation of higher quark combinations, tetraquarks and pentaquarks, is a strong indication of more exotic hadrons. Using Z_{2} and Z_{3} symmetries and standard model…
On Thermodynamics of AdS Black Holes in M-Theory
A. Belhaj, M. Chabab, H. EL Moumni +2
Motivated by a recent work on asymptotically AdS_4 black holes in M-theory, we investigate the thermodynamics and thermodynamical geometry of AdS black holes from M2 and M5-branes.…
On Hawking Radiation of 3D Rotating Hairy Black Holes
A. Belhaj, M. Chabab, H. EL Moumni +2
We study the Hawking radiation of 3D rotating hairy black holes. More concretely, we compute the transition probability of a bosonic and fermionic particle in such backgrounds. The…
Fractional Quantum Hall Filling Factors from String Theory using Toric Geometry
A. Belhaj, Z. Benslimane, M. El Idrissi +3
Using toric Cartan matrices as abelian gauge charges, we present a class of stringy fractional quantum Hall effect (FQHE) producing some recent experimental observed filling factor…
F-theory and N=1 Quivers from Polyvalent Geometry
Adil Belhaj, Moulay Brahim Sedra
We study four dimensional quiver gauge models from F-theory compactified on fourfolds with hyper-Kähler structure. Using intersecting complex toric surfaces, we derive a class of N…
