The String CP Problem
S. Abel, S. Khalil, O. Lebedev
We show that string models with low energy supersymmetry which accommodate the fermion mass hierarchy generally give non-universal soft trilinear couplings (A-terms). In conjunctio…
Chargino Contributions to Epsilon and Epsilon-Prime
S. Khalil, O. Lebedev
We analyze the chargino contributions to the K-\bar K mixing and epsilon-prime in the mass insertion approximation and derive the corresponding bounds on the mass insertion paramet…
Monopole Problem and Extensions of Supersymmetric Hybrid Inflation
R. Jeannerot, S. Khalil, G. Lazarides
We discuss, in the context of a concrete supersymmetric grand unified model based on the Pati-Salam gauge group SU(4)_c x SU(2)_L x SU(2)_R, two "natural" extensions of supersymmet…
Leptogenesis in Smooth Hybrid Inflation
R. Jeannerot, S. Khalil, G. Lazarides
We present a concrete supersymmetric grand unified model based on the Pati-Salam gauge group SU(4)_c x SU(2)_L x SU(2)_R and leading naturally to smooth hybrid inflation, which avo…
Muon anomalous magnetic moment in supersymmetric scenarios with an intermediate scale and nonuniversality
D. G. Cerdeno, E. Gabrielli, S. Khalil +2
We analyze the anomalous magnetic moment of the muon (a_μ) in supersymmetric scenarios. First we concentrate on scenarios with universal soft terms. We find that a moderate increas…
EDM Constraints in Supersymmetric Theories
S. Abel, S. Khalil, O. Lebedev
We systematically analyze constraints on supersymmetric theories imposed by the experimental bounds on the electron, neutron, and mercury electric dipole moments. We critically rea…
Determination of the String Scale in D-Brane Scenarios and Dark Matter Implications
D. G. Cerdeno, E. Gabrielli, S. Khalil +2
We analyze different phenomenological aspects of D-brane constructions. First, we obtain that scenarios with the gauge group and particle content of the supersymmetric standard mod…
Lepton-Flavor Violation with Non-universal Soft Terms
Daniel F. Carvalho, Mario E. Gomez, Shaaban Khalil
We study the lepton-flavor violation processes tau ->mu gamma and mu->e gamma in two different examples of models with non-universal soft breaking terms derived from strings. We sh…
