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…

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…

Precision Higgs Constraints in U(1) Extensions of the Standard Model with a Light Z'-Boson
Zoltán Péli, Zoltán Trócsányi
Anomaly free extensions of the standard model (SM) predict a new neutral gauge boson . When the obtains its mass from the spontaneous breaking of the new sym…
