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…

Scaling Behaviors in Active Model B+ via the Functional Renormalization Group

Gergely Fejős, Zsolt Szép, Naoki Yamamoto

We study the scaling behaviors of the active model B+ using the functional renormalization group (FRG) approach, based on the nonequilibrium effective action formulated via the Mar…

Naive Gaussian approximation in a quark-meson model

Győző Kovács, Zsolt Szép, Péter Kovács +1

A sequence of approximations is derived to go beyond the mean-field level in the case of a simple linear sigma model. A naive, local version of the Gaussian approximation is discus…

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…

Scale dependence of the Kondo interaction in the functional renormalization group formalism

Gergely Fejős, Taro Kimura, Zsolt Szép

Scale evolution of interactions between a Weyl fermion and a heavy magnetic impurity is calculated non-perturbatively using the functional renormalization group technique. Using an…
