• Dimensional reduction of the Standard Model coupled to a new singlet scalar field 

      Brauner, Tomas; Tenkanen, Tuomas; Tranberg, Anders; Vuorinen, Aleksi; Weir, David James (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 ...
    • On high-order perturbative calculations at finite density 

      Ghisoiu, Ioan; Gorda, Tyler; Kurkela, Aleksi; Romatschke, Paul; Säppi, Matias; Vuorinen, Aleksi (Journal article; Peer reviewed, 2017-02)
      We discuss the prospects of performing high-order perturbative calculations in systems characterized by a vanishing temperature but finite density. In particular, we show that the determination of generic Feynman integrals ...
