On Flux Compactification and Moduli Stabilization
A. Awad, N. Chamoun, S. Khalil
We study the effect of adding charged matter fields to both D3 and D7 branes in type IIB string theory compactification with fluxes. Generically, charged matter fields induce addit…
Effect of axial electric field on the binding energy of a shallow hydrogenic impurity in a Quantum Well Wire
I F I Mikhail, T G Emam
We present a study of the effect of an electric field on the binding energy of a shallow hydrogenic impurity in GaAs/Ga_{1-x}Al_{x}As quantum well wires. The wire is considered to…
Effect of temperature on the binding energy of a shallow hydrogenic impurity in a Quantum Well Wire
T G Emam
This work studies the effect of temperature on the binding energy of a shallow hydrogenic impurity located on the axis of a cylindrical semiconductor GaAs Al_x Ga_{1-x} As quantum…
Backbending phenomena in light nuclei at A~60 mass region
S. U. El-Kameesy, H. H. Alharbi, y +1
Recent studies of the backbending phenomenon in medium light weight nuclei near A~60 expanded greatly our interest about how the single particle orbits are nonlinearly affected by…
Probing Flavor Structure in Supersymmetric Theories
Shaaban Khalil
We analyze the possibility of probing the supersymmetric flavor structure through the constraints of the K and B meson systems and those of the electric dipole moments. We show tha…
Wormhole solution and Energy in Teleparallel Theory of Gravity
Gamal G. L. Nashed
An exact solution is obtained in the tetrad theory of gravitation. This solution is characterized by two-parameters of spherically symmetric static Lorentzian wormhole w…
Application of Theorems on Null-Geodesics on the Solar Limb Effect
F. I. Mikhail, M. I. Wanas, A. B. Morcos
A direct and more general calculation of the limb effect connected with red-shift observations is obtained. Result agrees completely, in its general form, with that obtained from o…
CP asymmetries and branching ratios of B --> K πin supersymmetric models
Shaaban Khalil
We analyze the supersymmetric contributions to the direct and mixing CP asymmetries and also to the branching ratios of the B --> K πdecays in a model independent way. We consider…
Space-Time Structure and Electromagnetism
M. I. Wanas, Samah A. Ammar
Two Lagrangian functions are used to construct geometric field theories. One of these Lagrangians depends on the curvature of space, while the other depends on curvature and torsio…
Fermion Masses and Mixing in Four and More Dimensions
N. Chamoun, S. Khalil
We give an overview of recent progress in the study of fermion mass and flavor mixing phenomena. Mass matrix ansatze are considered within the SM and SUSY GUTs where some predictiv…
Charged Axially Symmetric Solution, Energy and Angular Momentum in Tetrad Theory of Gravitation
Gamal G. L. Nashed
Charged axially symmetric solution of the coupled gravitational and electromagnetic fields in the tetrad theory of gravitation is derived. The metric associated with this solution…
