Deviation from Tri-Bimaximal Mixing and Large Reactor Mixing Angle
Ahmed Rashed
Recent observations for a non-zero have come from various experiments. We study a model of lepton mixing with a 2-3 flavor symmetry to accommodate the sizable mea…
Forward Energy Flow, Central Charged-Particle Multiplicities, and Pseudorapidity Gaps in W and Z Boson Events from pp Collisions at 7 TeV
CMS Collaboration
A study of forward energy flow and central charged-particle multiplicity in events with W and Z bosons decaying into leptons is presented. The analysis uses a sample of 7 TeV pp co…
Nonzero Theta13 for Neutrino Mixing in a Supersymmetric B-L Gauge Model with T_7 Lepton Flavor Symmetry
Qing-Hong Cao, Shaaban Khalil, Ernest Ma +1
We discuss how θ_{13} \neq 0 is accommodated in a recently proposed renormalizable model of neutrino mixing using the non-Abelian discrete symmetry T_7 in the context of a supersym…
The charged lepton mass matrix and non-zero with TeV scale New Physics
Ahmed Rashed, Alakabha Datta
We provide an explicit structure of the charged lepton mass matrix which is 2-3 symmetric except for a single breaking of this symmetry by the muon mass. We identify a flavor symme…
The One-zero Textures of Majorana Neutrino Mass Matrix and Current Experimental Tests
E. I. Lashin, N. Chamoun
We carry out a complete and systematic study of all the possible one-zero textures for the neutrino mass matrix in light of the recent neutrino oscillation data which hint to a rel…
Right-handed Sneutrino Inflation in SUSY B-L with Inverse Seesaw
Shaaban Khalil, Arunansu Sil
We propose a scenario for realizing inflation in the framework of supersymmetric B-L extension of the Standard Model. We find that one of the associated right-handed sneutrinos (th…
The quantum computational speed of a single Cooper Pair box
A. -S. F. Obada, D. A. M. Abo-Kahla, N. Metwally +1
The speed of computations is investigated by means of the orthogonality speed for a charged qubit interacting with a single cavity field prepared initially in a Fock state or Binom…
The Top Forward Backward Asymmetry with general Z ' couplings
Murugeswaran Duraisamy, Ahmed Rashed, Alakabha Datta
The measurement of the top forward-backward asymmetry in $\ttbar$ production measured at the Tevatron shows deviation from the Standard Model prediction. A transition vi…
Higgs Mass Corrections in the SUSY B-L Model with Inverse Seesaw
A. Elsayed, S. Khalil, S. Moretti
In the context of the Supersymmetric (SUSY) B-L (Baryon minus Lepton number) model with an inverse seesaw mechanism, we calculate the one-loop radiative corrections due to right-ha…
Radion Flavor Violation in Warped Extra Dimension
K. Huitu, S. Khalil, A. Moursy +2
We analyze the flavor violation in warped extra dimension due to radion mediation. We show that ΔS=2 and ΔB=2 flavor violating processes impose stringent constraints on radion mass…
Muon Anomalous Magnetic Moment and mu -> e gamma in B-L Model with Inverse Seesaw
W. Abdallah, A. Awad, S. Khalil +1
We study the anomalous magnetic moment of the muon, a_μ, and lepton flavor violating decay μ-> e γin TeV scale B-L extension of the Standard Model (SM) with inverse seesaw mechanis…
Energy and momentum of a spherically symmetric dilaton frame as regularized by teleparallel gravity
Gamal G. L. Nashed
We calculate energy and momentum of a spherically symmetric dilaton frame using the gravitational energy-momentum 3-form within the tetrad formulation of general relativity (GR). T…
Dimuon CP Asymmetry in B Decays and Wjj Excess in Two Higgs Doublet Models
Bhaskar Dutta, Shaaban Khalil, Yukihiro Mimura +1
We analyze the puzzle of the dimuon CP asymmetry in B_s decays in two Higgs doublet models. We show that the flavor changing neutral current (FCNC) induced by the Higgs coupling in…
Entanglement dynamics of one-dimensional driven spin systems in time-varying magnetic fields
Bedoor Alkurtass, Gehad Sadiek, Sabre Kais
We study the dynamics of entanglement for a one-dimensional spin chain with a nearest neighbor time dependent Heisenberg coupling J(t) between the spins in presence of a time depen…
Geometrical Properties of Coupled Oscillators at Synchronization
Hassan F. El-Nashar, Hilda A. Cerdeira
We study the synchronization of nearest neighbors coupled oscillators in a ring. We derive an analytic form for the phase difference among neighboring oscillators which shows t…
An AP-Structure with Finslerian Flavor II: Torsion, Curvature and Other Objects
M. I. Wanas, Mona M. Kamal
An absolute parallelism (AP-) space having Finslerian properties is called FAP-space. This FAP-structure is more wider than both conventional AP and Finsler structures. In the pres…
Right-handed Sneutrino Dark Matter in Supersymmetric B-L Model
Shaaban Khalil, Hiroshi Okada, Takashi Toma
We show that the lightest right-handed sneutrino in TeV scale supersymmetric B-L model with inverse seesaw mechanism is a viable candidate for cold dark matter. We find that it acc…
Dynamics of entanglement in a two-dimensional spin system
Qing Xu, Gehad Sadiek, Sabre Kais
We consider the time evolution of entanglement in a finite two dimensional transverse Ising model. The model consists of a set of 7 localized spin-1/2 particles in a two dimensiona…
Gravitational radiation fields in teleparallel equivalent of general relativity and their energies
G. G. L. Nashed
We derive two new retarded solutions in the teleparallel theory equivalent to general relativity (TEGR). One of these solutions gives a divergent energy. Therefore, we used the reg…
