• Quasiparticle properties of nonequilibrium gluon plasma 

  Peuron, Jarkko (University of Jyväskylä, 2018)

  We apply classical gluodynamics to early stages of ultrarelativistic heavy-ion collisions. We start by giving a brief overview of QCD. Then we proceed to the space-time evolution of ultrarelativistic heavy-ion collisions ...

• Developing a metatheoretical framework for second language development : a cultural-historical theory and dynamic systems theory perspective 

  Karimi-Aghdam-Ordaklou, Saeed (University of Jyväskylä, 2017)

  The main aim of this article-based dissertation is to construct and articulate a dialectical metatheoretical architecture for the study of second language development termed Purposive-Historical Systems Theory (PHiST) ...

• Determination of the non-abelian Debye screening mass using classical chromodynamics 

  Peuron, Jarkko (2014)

  Tässä työssä tutkitaan gluonin Debye-massaa, ja sen aika- ja miehityslukudis- tribuutioriippuvuutta käyttäen klassista väridynamiikkaa kahdessa paikkaulot- tuvuudessa. Työssä tutkitaan myös ominaista liikemääräskaalaa ja ...

• On the validity of perturbative studies of the electroweak phase transition in the Two Higgs Doublet model 

  Kainulainen, Kimmo; Keus, Venus; Niemi, Lauri; Rummukainen, Kari; Tenkanen, Tuomas V. I.; Vaskonen, Ville (Springer, 2019)

  Making use of a dimensionally-reduced effective theory at high temperature, we perform a nonperturbative study of the electroweak phase transition in the Two Higgs Doublet model. We focus on two phenomenologically allowed ...

• Massless positivity in graviton exchange 

  Herrero-Valea, Mario; Santos-Garcia, Raquel; Tokareva, Anna (American Physical Society (APS), 2021)

  We formulate positivity bounds for scattering amplitudes including exchange of massless particles. We generalize the standard construction through dispersion relations to include the presence of a branch cut along the real ...
