Toric Geometry, Enhanced non Simply laced Gauge Symmetries in Superstrings and F-theory Compactifications
A. Belhaj, E. H Saidi
We study the geometric engineering of supersymmetric quantum field theories (QFT), with non simply laced gauge groups, obtained from superstring and F-theory compactifications on l…
On HyperKahler Singularities
A. Belhaj, E. H. Saidi
Using a geometric realization of the symmetry and a procedure of factorisation of the gauge and charges, we study the small instanton singularities of the Higgs…
Explicit Derivation of Yang-Mills Self-Dual Solutions on non-Commutative Harmonic Space
A. Belhaj, M. Hssaini, E. L. Sahraoui +1
We develop the noncommutative harmonic space (NHS) analysis to study the problem of solving the non-linear constraint eqs of noncommutative Yang-Mills self-duality in four-dimensio…
Hyperkahler Singularities in Superstrings Compactification and 2d N=4 Conformal Field Theory
A. Belhaj, E. H. Saidi
We study the singularities of the Higgs branch of supersymmetric U(1)^r gauge theories with eight supercharges. We derive new solutions for the moduli space of vacua preserving man…
