Polarization of the CMB in the Standard Model Extension
Iman Motie, Jafar Khodagholizadeh, S. Mahmoudi +2
In standard cosmology, Cosmic Microwave Background photons near the last scattering surface exhibit only linear polarization due to Compton scattering, leading to the assumption th…
The optical analogy between a Lorentz-violating cosmos and a Magneto-Electric medium
Iman Motie, Brahim Lamine, Alain Blanchard +2
The goal of our study is to investigate the effects of Lorentz symmetry violation by examining the behavior of photons within the framework of the Standard Model Extension (SME). W…
Generation of the CMB cosmic Birefringence through Axion-like particles, Sterile and Active neutrinos
Somayyeh Mahmoudi, Mahdi Sadegh, Jafar Khodagholizadeh +3
The cosmic birefringence (CB) angle refers to the rotation of the linear polarization plane of Cosmic Microwave Background (CMB) radiations when parity-violating theories are consi…
Muon anomalous magnetic moment and Right handed sterile neutrino
Iman Motie, S. Mahmoudi, Mahdi Sadegh +3
The muon's magnetic moment is a fundamental quantity in particle physics and the deviation of its value from quantum electrodynamics (QED), motivates research beyond the standard m…
Muon anomalous magnetic moment in the standard model extension
S. Aghababaei, M. Haghighat, I. Motie
We consider the standard model extension to explore the anomalous magnetic dipole moment of the muon. In the QED part of the theory for the CP and CPT-even Lorentz parameter $c_{μν…
Generation of circular polarization in CMB radiation via nonlinear photon-photon interaction
Mehdi Sadegh, Rohoollah Mohammadi, Iman Motie
Standard cosmological models do predict a measurable amount of anisotropies in the intensity and linear polarization of the Cosmic Microwave Background radiation (CMB) via Thomson…
Circular polarization from linearly polarized laser beam collisions
Rohoollah Mohammadi, Iman Motie, She-Sheng Xue
To probe the nonlinear effects of photon-photon interaction in the quantum electrodynamics, we study the generation of circular polarized photons by the collision of two linearly p…
Charged lepton electric dipole moment enhancement in the Lorentz violated extension of the standard model
M. Haghighat, I. Motie, Z. Rezaei
We consider the Lorentz violated extension of the standard model. In this framework, there are terms that explicitly violate CP-symmetry. We examine the CPT-even -term to f…
High energy neutrino oscillation at the presence of the Lorentz Invariance Violation
Iman Motie, She-Sheng Xue
Due to quantum gravity fluctuations at the Planck scale, the space-time manifold is no longer continuous, but discretized. As a result the Lorentz symmetry is broken at very high e…
Neutrino oscillations in nuclear media
Iman Motie, She-Sheng Xue
On basis of effective interactions of charged lepton and hadron currents, we obtain an effective interacting Hamiltonian of neutrinos in nuclear media up to the leading order. Usin…
Euler-Heisenberg Lagrangian and photon circular polarization
Iman Motie, She-Sheng Xue
Considering the effective Euler-Heisenberg Lagrangian, i.e., non-linear photon-photon interactions, we study the circular polarization of electromagnetic radiation based on the tim…
Generation of circular polarization of the CMB
E. Bavarsad, M. Haghighat, Z. Rezaei +3
According to the standard cosmology, near the last scattering surface, the photons scattered via Compton scattering are just linearly polarized and then the primordial circular pol…
