Inner-shell Annihilation of Positrons in Argon, Iron and Copper Atoms
M. A. Abdel-Raouf, M. M. Abdel-Mageed, S. Y. El-Bakry
The annihilation parameters of positrons with electrons in different shells of Argon, Iron and Copper atoms are calculated below the positronium (Ps) formation thresholds. Quite ac…
Radiative B-L symmetry breaking in supersymmetric models
S. Khalil, A. Masiero
We propose a scheme where the three relevant physics scales related to the supersymmetry, electroweak, and baryon minus lepton (B-L) breakings are linked together and occur at the…
Zero minors of the neutrino mass matrix
E. I. Lashin, N. Chamoun
We examine the possibility that a certain class of neutrino mass matrices, namely those with two independent vanishing minors in the flavor basis, regardless of being invertible or…
Textures with two traceless submatrices of the neutrino mass matrix
H. A. Alhendi, E. I. Lashin, A. A. Mudlej
We propose a new texture for the light neutrino mass matrix. The proposal is based upon imposing zero-trace condition on the two by two sub-matrices of the complex symmetric Majora…
Neutrino masses, mixing and leptogenesis in TeV scale B-L extension of the standard model
M . Abbas, S. Khalil
We address the issue of the neutrino masses and mixing in TeV scale extension of the Standard Model. We show that if Dirac neutrino masses are of order Gev, then th…
Charged Axially Symmetric Solution and Energy in Teleparallel Theory Equivalent to General Relativity
Gamal Gergess Lamee Nashed
An exact charged solution with axial symmetry is obtained in the teleparallel equivalent of general relativity (TEGR). The associated metric has the structure function $G(ξ)=1-ξ^2-…
Analytical calculation of the transition to complete phase synchronization in coupled oscillators
Paulsamy Muruganandam, Fernando F. Ferreira, Hassan F. El-Nashar +1
Here we present a system of coupled phase oscillators with nearest neighbors coupling, which we study for different boundary conditions. We concentrate at the transition to total s…
Reissner-Nordström Spacetime in the Tetrad Theory of Gravitation
Gamal G. L. Nashed, Takeshi Shirafuji
We give two classes of spherically symmetric exact solutions of the couple gravitational and electromagnetic fields with charged source in the tetrad theory of gravitation. The fir…
Higgs and Z' Phenomenology in B-L extension of the Standard Model at LHC
W. Emam, S. Khalil
The phenomenology of the low scale U(1)_{B-L} extension of the standard model and its implications at LHC is presented. In this model, an extra gauge boson corresponding to B-L gau…
A Note on General Covariant Stability Theory
M. I. Wanas, M. A. Bakry
In the present work we suggest a general covariant theory which can be used to study the stability of any physical system treated geometrically. Stability conditions are connected…
Nuclear-induced time evolution of entanglement of two-electron spins in anisotropically coupled quantum dot
Gehad Sadiek, Zhen Huang, Omar Aldossary +1
We study the time evolution of entanglement of two spins in anisotropically coupled quantum dot interacting with the unpolarized nuclear spins environment. We assume that the excha…
