Transport equations for chiral fermions to order \hbar and electroweak baryogenesis: Part I
T. Prokopec, M. G. Schmidt, S. Weinstock
This is the first in a series of two papers. We use the Schwinger-Keldysh formalism to derive semiclassical Boltzmann transport equations for massive chiral fermions and scalar par…
Photon mass generation during inflation: de Sitter invariant case
Tomislav Prokopec, Ewald Puchwein
We calculate the one-loop vacuum polarization tensor of scalar electrodynamics in a locally de Sitter space-time, endowed with a nearly minimally coupled, light scalar field. We sh…
Dynamics of super-horizon photons during inflation with vacuum polarization
Tomislav Prokopec, Richard P. Woodard
We study asymptotic dynamics of photons propagating in the polarized vacuum of a locally de Sitter Universe. The origin of the vacuum polarization is fluctuations of a massless, mi…
Axial Currents from CKM Matrix CP Violation and Electroweak Baryogenesis
Thomas Konstandin, Tomislav Prokopec, Michael G. Schmidt
The first principle derivation of kinetic transport equations suggests that a CP-violating mass term during the electroweak phase transition can induce axial vector currents. Since…
Production of Massless Fermions during Inflation
T. Prokopec, R. P. Woodard
We compute the one loop self energy, in a locally de Sitter background, for a massless fermion which is Yukawa-coupled to a massless, minimally coupled scalar. We then solve the mo…
Coherent Baryogenesis
Bjorn Garbrecht, Tomislav Prokopec, Michael G. Schmidt
We propose a new baryogenesis scenario based on coherent production and mixing of different fermionic species. The mechanism is operative during phase transitions, at which the fer…
