New Physics contribution to decays in SCET
K. Huitu, S. Khalil
We analyze the difference between the CP asymmetries of the and decays within the Soft Collinear Effective Theory. We find that in the Stan…
Brane World black holes in Teleparallel Theory Equivalent to General Relativity and their Killing vectors, Energy, Momentum and Angular-Momentum
Gamal G. L. Nashed
The energy-momentum tensor, which is coordinate independent, is used to calculate energy, momentum and angular-momentum of two different tetrad fields. Although, the two tetrad fie…
One vanishing minor in the neutrino mass matrix
E. I. Lashin, N. Chamoun
We study a specific texture of the neutrino mass matrix, namely the models with one subdeterminant equal to zero. We carry out a complete phenomenological analysis with…
(Z_2)^3 Symmetry of the Tripartite Model
E. I. Lashin, E. Malkawi, S. Nasri +1
We derive in a simple way the symmetry which characterizes uniquely the phenomenologically successful tripartite form leading to the tribimaximal mixing in the neutrino m…
B -> K pi Puzzle and New Sources of CP Violation in Supersymmetry
S. Khalil, A. Masiero, H. Murayama
The difference between the CP asymmetries of the and decays has been recently confirmed with an evidence larger than 's. We discuss it as a…
Lepton flavor violation in supersymmetric B-L extension of the standard model
Shaaban Khalil
Supersymmetric B-L extension of the Standard Model (SM) is one of the best candidate for physics beyond the SM that accounts for TeV scale seesaw mechanism and provides an attracti…
A Pure Geometric Approach to Stellar Structure
M. I. Wanas, Samah A. Ammar
The present work represents a step to deal with stellar structure using a pure geometric approach. A geometric field theory is used to construct a model for a spherically symmetric…
Slowly Varying Dilaton Cosmologies and their Field Theory Duals
Adel Awad, Sumit R. Das, Archisman Ghosh +2
We consider a deformation of the solution of IIB supergravity obtained by taking the boundary value of the dilaton to be time dependent. The time dependence is ta…
Supersymmetry and CP violation in B^0_s - \bar{B}^0_s mixing and B^0_s -> J/ψϕdecay
Alakabha Datta, Shaaban Khalil
Supersymmetric contributions to time independent asymmetry in process are analyzed in the view of the recent Tevatron experimental measurements. We show that the e…
Analytic Determination of the Critical Coupling for Oscillators in a Ring
Hassan F. El-Nashar, Hilda A. Cerdeira
We study a model of coupled oscillators with bidirectional first nearest neighbours coupling with periodic boundary conditions. We show that a stable phase-locked solution is decid…
Dark Matter Annihilation and the PAMELA, FERMI and ATIC Anomalies
A. A. El-Zant, S. Khalil, H. Okada
If dark matter (DM) annihilation accounts for the tantalizing excess of cosmic ray electron/positrons, as reported by the PAMELA, ATIC, HESS and FERMI observatories, then the impli…
Self-dual Lorentzian Wormholes and Energy in Teleparallel Theory of Gravity
Gamal Gergess Lamee Nashed
Two spherically symmetric, static Lorentzian wormholes are obtained in tetrad theory of gravitation as a solution of the equation , where $ρ=T_{ij}u^iu^j, ρ_t=(T_{ij}-{1/2…
Generalized Lepton Number and Dark Left-Right Gauge Model
Shaaban Khalil, Hye-Sung Lee, Ernest Ma
In a left-right gauge model of particle interactions, the left-handed fermion doublet (nu,e)_L is connected to its right-handed counterpart (n,e)_R through a scalar bidoublet so th…
Electron EDM and soft leptogenesis in supersymmetric B-L extension of the standard model
Yuji Kajiyama, Shaaban Khalil, Martti Raidal
We analyze the connection between electric dipole moment of the electron and the soft leptogenesis in supersymmetric extension of the standard model. In this model, the …
