Dimensional reduction of the Two-Higgs Doublet Model with a softly broken Z2 symmetry at one-loop
Helset, Andreas (Master thesis, 2017)In the collaboration between NTNU, the University of Stavanger, and the University of Helsinki we pursue a satisfactory answer to the problem of baryogenesis, i.e. the origin of the asymmetry in the amount of baryons and ... -
Nonperturbative analysis of the electroweak phase transition in the two Higgs doublet model
Andersen, Jens Oluf; Gorda, Tyler; Helset, Andreas; Niemi, Lauri; Tenkanen, Tuomas V.I.; Tranberg, Anders; Vuorinen, Aleksi; Weir, David J. (Journal article; Peer reviewed, 2018)We perform a nonperturbative study of the electroweak phase transition (EWPT) in the two Higgs doublet model (2HDM) by deriving a dimensionally reduced high-temperature effective theory for the model, and matching to known ... -
Three-dimensional effective theories for the two Higgs doublet model at high temperature
Gorda, Tyler; Helset, Andreas; Niemi, Lauri; Tenkanen, Tuomas V.I.; Weir, David J. (Journal article; Peer reviewed, 2019)Due to the infrared problem of high-temperature field theory, a robust study of the electroweak phase transition (EWPT) requires use of non-perturbative methods. We apply the method of high-temperature dimensional reduction ...
