An upper limit on cosmological chiral gravitational wave background
Mohammad Ali Gorji, Ashu Kushwaha, Teruaki Suyama
Within the standard framework in which electroweak sphaleron processes relate lepton and baryon number, we derive an upper limit on the amplitude of a chiral gravitational wave bac…
Dark photon dark matter from charged inflaton
Hassan Firouzjahi, Mohammad Ali Gorji, Shinji Mukohyama +1
We present a scenario of vector dark matter production during inflation containing a complex inflaton field which is charged under a dark gauge field and which has a symmetry break…
Vector dark matter production from inflation with symmetry breaking
Borna Salehian, Mohammad Ali Gorji, Hassan Firouzjahi +1
We present a scenario of vector dark matter production from symmetry breaking at the end of inflation. In this model, the accumulated energy density associated with the quantum flu…
Analytic study of dark photon and gravitational wave production from axion
Borna Salehian, Mohammad Ali Gorji, Shinji Mukohyama +1
Axion-like fields heavier than about eV are expected to oscillate in the radiation dominated epoch when the Hubble parameter drops below their mass. Considering the Chern…
