Signature of Non-Minimal Scalar-Gravity Coupling with an Early Matter Domination on the Power Spectrum of Gravitational Waves
Amirsalar Nikandish, Shiva Rostam Zadeh, Reza Naderi +2
The signal strength of primordial gravitational waves experiencing an epoch of early scalar domination is reduced with respect to radiation domination. In this paper, we demonstrat…
The generation of baryon asymmetry and hypermagnetic field by the chiral vortical effect in the presence of sphalerons
S. Abbaslu, A. Rezaei, S. Rostam Zadeh +1
We show how the temperature-dependent chiral vortical effect can generate hypermagnetic fields and matter-antimatter asymmetries, in the symmetric phase of the early Universe, in t…
Contribution of the thermal mass to the chiral vortical effect and magnetobaryogenesis
S. Abbaslu, S. Rostam Zadeh, S. S. Gousheh
We show that the chiral vortical effect can exist in a nonchiral electroweak plasma in thermal equilibrium using the effective thermal masses of the fermions in the symmetric phase…
The effects of non-helical component of hypermagnetic field on the evolution of the matter-antimatter asymmetry, vorticity, and hypermagnetic field
S. Abbaslu, S. Rostam Zadeh, A. Rezaei +1
We study the evolution of the matter-antimatter asymmetry (η), the vorticity, and the hypermagnetic field in the symmetric phase of the early Universe, and in the temperature range…
The generation of matter-antimatter asymmetries and hypermagnetic fields by the chiral vortical effect of transient fluctuations
S. Abbaslu, S. Rostam Zadeh, M. Mehraeen +1
We study the contribution of temperature-dependent chiral vortical effect to the generation and evolution of the hypermagnetic fields and the matter-antimatter asymmetries, in the…
A Minimal System Including Weak Sphalerons for Investigating the Evolution of Matter Asymmetries and Hypermagnetic Fields
S. Rostam Zadeh, S. S. Gousheh
We study simultaneous evolution of large scale hypermagnetic fields and the asymmetries of quarks, leptons and Higgs boson in the temperature range from 10TeV to 100GeV. Above 10Te…
The effects of the U(1) Chern-Simons term and its baryonic contribution on matter asymmetries and hypermagnetic fields
S. Rostam Zadeh, S. S. Gousheh
In this paper, we study the significance of the U(1) Chern-Simons term in general, and its baryonic contribution in particular, for the evolution of the matter asymmet…
On the Contributions to the Chern-Simons Term and the Evolution of Fermionic Asymmetries and Hypermagnetic Fields
S. Rostam Zadeh, S. S. Gousheh
We study simultaneous evolution of electron, neutrino and quark asymmetries, and large scale hypermagnetic fields in the symmetric phase of the electroweak plasma in the temperatur…
