On the Fermion Level Crossing in the Electroweak Instanton Background
P. E. Mogaddam, S. S. Gousheh
We investigate fermion level crossing in the electroweak instanton background, taking into account the Euclidean-time dependence of the fermion energy throughout our analysis, from…
Fermion Zero Modes and Fermion number of the 't Hooft-Polyakov Monopole
P. E. Mogaddam, S. S. Gousheh
Fermion bound states in the background of the 't Hooft-Polyakov SU(2) monopole are investigated for various values of gauge coupling constant , the Higgs self-coupling constant…
Global charge conservation in the symmetric phase of the early Universe
S. Abbaslu, M. Abdolhoseini, P. E. Moghaddam +1
In the Standard Model at high temperatures, anomalous effects contribute to the violation of baryon number () and lepton number (), separately, while remains conserved.…
Thermal Fermion Propagators and Flavor-Changing via Loop Corrections in the Early Universe
A. Hataei, S. S. Gousheh
We present the Minimally Extended Standard Model in the mass basis in the symmetric phase of the early Universe, demonstrating that the CP-violating CKM and PMNS matrices emerge no…
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…
