Cosmic Birefringence as a probe of dark matter nature: Sterile neutrino and dipolar dark matter
Jafar Khodagholizadeh, S. Mahmoudi, R. Mohammadi +1
Recently, non-zero rotation angle [Phys. Rev. Lett. \textbf{128}, no.9, 091302 (2022)] has been reported for linear polarization of…
Impact of the vector dark matter on polarization of the CMB photon
S. Modares Vamegh, M. Haghighat, S. Mahmoudi +1
We consider a vector dark matter (VDM) with a direct coupling with photon. We examine the effect of such an interaction on the CMB polarization to put new constrains on the propert…
Circular polarization of cosmic photons due to their interactions with Sterile neutrino dark matter
M. Haghighat, S. Mahmoudi, R. Mohammadi +2
In this paper, we explore the possibility of the polarization conversion of a wide energy range of cosmic photons to the circular polarization through their interactions with right…
Probing Lorentz violation effects via a laser beam interacting with a high-energy charged lepton beam
Seddigheh Tizchang, Rohoollah Mohammadi, She-Sheng Xue
In this work, the conversion of linear polarization of a laser beam to circular one through its forward scattering by a TeV order charged lepton beam in the presence of Lorentz vio…
Dipolar dark matter and CMB B-mode polarization
S. Mahmoudi, M. Haghighat, S. Modares Vamegh +1
We consider dark matter as singlet fermionic particles which carrying magnetic dipole moment to explore its contribution on the polarization of cosmic microwave background (CMB) ph…
Using an intense laser beam in interaction with muon/electron beam to probe the Noncommutative QED
S. Tizchang, S. Batebi, M. Haghighat +1
It is known that the linearly polarized photons can partly transform to circularly polarized ones via forward Compton scattering in a background such as the external magnetic field…
Cosmic microwave background polarization in Noncommutative space-time
S. Batebi, M. Haghighat, R. Mohammadi +1
In the standard model of cosmology (SMC) the B-mode polarization of the CMB can be explained by the gravitational effects in the inflation epoch. However, this is not the only way…
Using strong intense lasers to probe sterile neutrinos
Pouya Bakhti, Rohoollah Mohammadi, She-Sheng Xue
A linearly polarized laser beam acquires its circular polarization by interacting with a neutrino beam for the reason that the gauge-couplings of left-handed neutrinos are parity-v…
Laser photons acquire circular polarization by interacting with a Dirac or Majorana neutrino beam
Rohoollah Mohammadi, She-Sheng Xue
It is shown that for the reason of neutrinos being left-handed and their gauge-couplings being parity-violated, linearly polarized photons acquire their circular polarization by in…
Nucleon-Nucleon Scattering in a Strong External Magnetic Field and the Neutrino Emissivity
E. Bavarsad, M. Haghighat, R. Mohammadi
The nucleon-nucleon scattering in a large magnetic background is considered to find its potential to change the neutrino emissivity of the neutron stars. For this purpose we consid…
Noncommutative QED+QCD and -function for QED
M. M. Ettefaghi, M. Haghighat, R. Mohammadi
QED based on -unexpanded noncomutative space-time in contrast with the noncommutative QED based on -expanded U(1) gauge theory via the Seiberg-Witten map, is one-loop renorma…
