Beyond the standard model with sum rules
Damian Ejlli
The possibility of physics beyond the standard model is studied. The requirement of finiteness of the zero point energy density and pressure or the requirement of the Lorentz invar…
Milli-charged fermion vacuum polarization in cosmic magnetic fields and generation of CMB elliptic polarization
Damian Ejlli
The contribution of one loop milli-charged fermion vacuum polarization in cosmic magnetic field to the cosmic microwave background (CMB) polarization is considered. Exact and pertu…
Axion mediated photon to dark photon mixing
Damian Ejlli
The interaction between the dark/mirror sector and the ordinary sector is considered, where the two sectors interact with each other by sharing the same QCD axion field. This featu…
Bounds on QCD axion mass and primordial magnetic field from CMB -distortion
Damian Ejlli
The oscillation of the CMB photons into axions can cause CMB spectral distortion in the presence of large scale magnetic field. With the COBE limit on the parameter and a homog…
CMB constraints on mass and coupling constant of light pseudoscalar particles
Damian Ejlli, Alexander D. Dolgov
Transformation of CMB photons into light pseudoscalar particles at post big bang nucleosynthesis epoch is considered. Using the present day value of a large scale magnetic field to…
