Plasma heating during the chiral plasma instability
Balin Armstrong, Andrew J. Long, Károly Seller +1
The presence of a chiral asymmetry in a relativistic plasma opens a tachyonic instability toward the growth of a helical magnetic field. We study the transfer of energy from the ch…
Energy spectrum of magnetic fields from electroweak symmetry breaking
Károly Seller, Günter Sigl
We study the magnetic fields produced in the early Universe during the electroweak symmetry breaking by considering random configurations of an inhomogeneous Higgs field. By exploi…
CP asymmetry factor in decays at finite temperature
Károly Seller, Zsolt Szép, Zoltán Trócsányi
We present in the conventional equilibrium approach to leptogenesis the complete leading order prediction for the CP asymmetry factor in finite-temperature decays involving Majoran…
On the contribution of galaxies to the magnetic field in cosmic voids
Károly Seller, Günter Sigl
Astrophysical processes can contribute to magnetic fields within cosmic voids either through magnetized outflows from the astrophysical large-scale structure or through superpositi…
CP violation at finite temperature
Károly Seller, Zsolt Szép, Zoltán Trócsányi
We present a comprehensive study of the finite temperature CP-asymmetry factor needed in the semi-classical treatment of leptogenesis originating from Majorana fermion decays into…
