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…
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-…
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…
