En utilisant la géométrie non commutative de l’espace-temps de Seiberg-Witten, pour la gravitation de jauge d’une corde cosmique charge en rotation on a déterminé explicitement en fonction du paramètre de la non commutativité ...
We study in this work the exact solutions of two-dimensional relativistic particuls of spin-0 in the cosmic string background under the effects of scalar potentials as modification in the momentum operator 𝑝𝜇→𝑝𝜇−𝑒𝐴𝜇 ...
Recent cosmological data show that the universe is expanding at an accelerating rate. This contradicts the results of general relativity, at least for a Universe composed only of matter. To attack this problem, two general ...
A PT symmetric and pseudo hermitien hamiltonien is constructed in the context of the seubery. Written non commutatitive space-time and some physical application are presented.
In this work, we will investigate the generalized Störmer problem for a charged dust grain near a rotating spherical magnetic planet with the effect of a quadrupolar magnetic term with a simultaneous influence of electromagnetic ...
A general class of potentials covering the Pöschl-Teller type and Scarf type is considered. The analytical expression of the energy eigenvalues is established with the help of the exact quantization formula. Then, using ...
NGC 5506 is a Seyfert galaxy whose AGN how strong X-ray variability and its spectrum shows both narrow and broad components of the Iron K alpha line, making it a an excellent target for X-ray reverberation. Using a new ...
In this paper we investigated the solution of the Dirac equation in the time dependent non commutative phase-space using the Lewis–Riesenfeld invariant method. Wherein the Dirac time dependent hamiltonian obtained from a ...
In this work, we solve the DKP equation (1+1) dimension for non-local potential of the form of Lorentz scalar plus vector (𝛽𝑔+ℎ)(𝑥)𝑣(𝑥′). The energy spectrum is found and discussed for this equation.
An extension of the gauge group SU(3)c⊗ SU(2)L⊗U(1)Y of the standard model to the symmetry group SU(4)L⊗U(1)X (3-4-1 for short) is presented. With the minimal scalar sector. The mass matrix of neutral gauge bosons is exactly ...

Diphoton Higgs Decay is studied in the context of the compact 341 Model and in the light of the recent resonances discovered at the LHC. Some new predictions are also discussed.
In this work, we will begin by introducing the various clues that lead to the hypothesis of dark matter. Then we will present several proposals that have been made to try to answer the question "what is made of this dark ...
We present a space-time transformation to the harmonic oscillator with a time-dependent mass and frequency and we transform the problem to that of constant mass and time-dependent potential of the form𝛺2(𝑡)𝑥2. The ...
In the framework of the singlet scalar extended standard model, we calculate the cross section of the vector boson fusion into top quark pairs relatively to the gluons fusion one. We also study the importance of different ...
In this paper, we calculate the propagator of a system of particle moving in a class of non-central potential. This study is done in the framework of path integrals. It has been possible to treat this potential in spherical ...
In the present study, SCALE6.1 package is used for the analysis of experimental neutron transmission data and for the determination of neutron attenuation characteristics of various neutron absorbing materials. The neutron ...
This work is devoted to the study of the nuclear structure around the doubly magic 132Sn nucleus in the frame of the shell model. We are interested in studying and understanding the role of the three body effects on the ...
Quality evaluation of the k0-standardized neutron activation analysis (k0-NAA) at Es-Salam research reactor has been implemented by analyzing SRM-NIST, the standard reference material of National Institute of Standards and ...
In radiotherapy, lung cancer is associated with local control rates very low. The difficulty of this type of treatment is to irradiate relatively radio-resistant lung lesions very radiosensitive. Thus, the issue of adequate ...
The majority of exposure to radiation comes from natural sources. Therefore, the knowledge of radionuclide distribution and radiation levels in the environment is important. The purpose of the study is twofold: first to ...
