Phenomenological Aspects of Standard Model Extension Zahra Rezaei Isfahan University of Technology Isfahan 84156 83111 Iran Abstract Symmetries are the useful tools to explain the physical rules of the nature On the other hand each discrepancy of them helps to concept the events and to extend the physics We have checked some deviation from the Lorentz symmetry in the context of the Standard Model Extension SME We have shown that if the Lorentz violation exists the circular polarization of the cosmic microwave background will be observed in the future There are some percentages of the circular polarization in the pulsars profiles There isn t any the ory to explain the origin and the mechanism to produce the circular polarization in the pulsars We have calculated the photon interactions in the presence of the Lorentz violation Using the huge mag netic fields of the pulsars and the relation between the Lorentz violation parameter kF and the Non commutative parameter we have demonstrated the production of circular polarization Fur thermore changing the direction of the circular polarization can occur The CPT even Lorentz violation parameter d violates the CP symmetry Electric Dipole Moment EDM of electron has calculated in the presence of this parameter and it has shown the electric dipole moment of the electron can be as large as 10 14 e cm Finally the evolution equations of the vorticities of the electrons ions and photons in a pre decoupling plasma are derived in a fully inhomogeneous geometry The maximal magnetic field induced by the total vorticity turns out to be at most of the order of 10 37 G Keywords Lorentz invariance violation Standard Model extension circular polarization of Cosmic Microwave Background Radiation Pulsars circular polarization Electric Dipole Moment of Electron Magnetic field from the pre decoupling plasma
