Rare decay with polarized in the fourth generation model
T. Barakat
The rare decay when meson is longitudinally or transversely polarized is analysed in the context of the fourth generation model. A significant enhancemen…
Heavy meson masses via Dick interquark potential
T. Barakat, M. Chabab
We study Dick quark-antiquark potential (up to a color factor) in the heavy meson sector. This potential em…
Nonrelativistic shifted-l expansion technique for three- and two-dimensional Schrodinger equation
Omar Mustafa, Thabit Barakat
The shifted-l expansion technique (SLET) has been developed to get eigenvalues of Schrodinger equation in three (3D) and two dimensions (2D). SLET simply consists of 1/\bar{l} as a…
Relativistic shifted-l expansion technique for Dirac and Klein-Gordon equations
Omar Mustafa, Thabit Barakat
The shifted-i expansion technique (SLET) is extended to solve for Dirac particle trapped in spherically symmetric scalar and/or 4-vector potentials. A parameter λ=0,1 is introduced…
Exact energy eigenvalues of the generalized Dirac-Coulomb equation via a modified similarity transformation
Omar Mustafa, Thabit Barakat
With the aid of a modified similarity transformation we obtained exact energy eigenvalues of the generalized Dirac-Coulomb equation. This equation consists of the time component of…
