1. Hybrid seesaw neutrino model in SUSY SU(5)×A4 / Laamara, R. Ahl ; Loualidi, M. A. ; Miskaoui, M. ; Saidi, E. H.
Motivated by recent results from neutrino experiments, we study the neutrino masses and mixing in the framework of a SUSY SU(5)×A4 model. [...]

2. Partial breaking in the rigid limit of gauged supergravity / Laamara, R Ahl ; Saidi, E H ; Vall, M
Using a new method to rescale fields in gauged supergravity with vector multiplets and hypermultiplets, we develop the explicit derivation of the rigid limit of quaternionic isometry Ward identities agreeing with known results. [...]

5. BPS spectra of N=2 SO 7 and SP 4 models / Ahl Laamara, R. ; Mellal, O. ; Saidi, E.H.
Extending the folding method of ADE Dynkin diagrams of Lie algebras to BPS quivers of 4d N=2 supersymmetric gauge theory with ADE type gauge invariance, we study the BPS spectra for gauge symmetries with non-simply laced Lie algebras. [...]

10. On Higgs self-coupling parameter λ of the standard model / Saidi, El Hassan
Thinking about the Higgs field doublet Hi of the standard model as obeying, in addition to the usual properties, a Weyl-type equation on the Goldstone 3-sphere of the UY(1)×SUL(2) gauge symmetry, we study underlying features of the free parameters μ2 and λ of the classical Higgs potential. [...]
