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. [...]

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 nonsimply laced Lie algebras. [...]

MSSMlike from SU 5 × D 4 models
/ Ahl Laamara, R. ; Miskaoui, M. ; Saidi, E.H.
Using finite discrete group characters and symmetry breaking by hyperflux as well as constraints on topquark family, we study minimal low energy effective theory following from SU5×D4 models embedded in Ftheory with nonabelian flux. [...]

/ Ahl Laamara, R. ; El Kinani, M.N. ; Saidi, E.H. ; Vall, M.
We consider the U(1)n extension of the effective N=2 supersymmetric U(1)×U(1) model of arXiv:1204.2141 ; and study the explicit relationship between partial breaking of N=2 supersymmetry constraint and D3 brane tadpole anomaly of type IIB string on Calabi–Yau threefolds in presence of HRR and HNS fluxes.

On Higgs selfcoupling 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 Weyltype equation on the Goldstone 3sphere of the UY(1)×SUL(2) gauge symmetry, we study underlying features of the free parameters μ2 and λ of the classical Higgs potential. [...]
