Chiral and deconfinement transitions in a magnetic background using the functional renormalization group with the Polyakov loop
(Journal article; Peer reviewed, 2014-04)We use the Polyakov loop coupled quark-meson model to approximate low energy QCD and present results for the chiral and deconfinement transitions in the presence of a constant magnetic background B at finite temperature T ... -
Dimensional reduction of the Standard Model coupled to a new singlet scalar field
(Journal article; Peer reviewed, 2017)We derive an effective dimensionally reduced theory for the Standard Model augmented by a real singlet scalar. We treat the singlet as a superheavy field and integrate it out, leaving an effective theory involving only the ... -
Effective field theory and electroweak baryogenesis in the singlet-extended Standard Model
(Journal article; Peer reviewed, 2016-02)Electroweak baryogenesis is a simple and attractive candidate mechanism for generating the observed baryon asymmetry in the Universe. Its viability is sometimes investigated in terms of an effective field theory of the ... -
Leptogenesis in crossing and runaway regimes.
(Journal article; Peer reviewed, 2014-07)We study the impact of effective thermal masses and widths on resonant leptogenesis. We identify two distinct possibilities which we refer to as ‘crossing’ and ‘runaway’ regimes. In the runaway regime the mass difference ...
