Täma Pro Gradu-tutkielma käsittelee mahdollista sähköheikko-faasimuunnoksen aikana tapahtuva baryogeneesia. Työn päämääränäon johtaa faasimuunnoksen aikana hiukkasten helisiteetti-tiloihin vaikuttava CP-symmetriaa rikkova, semiklassinen voima plasma-koordinaatistossa. Työssä johdetaan plasman aikakehitysyhtälöt käyttäen Schwinger-Keldysh formalismia plasman dynamiikalle. This thesis will examine the dynamics of particles during a first-order electroweak phase transition, with regard to the electroweak baryogenesis scenario. We will derive the CP-violating semiclassical force on helicity states in the plasma frame. We will also study the dynamics of the plasma in the Schwinger-Keldysh formalism to find the equations for the time-evolution of the plasma.

A strong electroweak phase transition from the inflaton field
Tenkanen, Tommi; Tuominen, Kimmo; Vaskonen, Ville (Institute of Physics Publishing Ltd.; Scuola Internazionale Superiore di Studi Avanzati (SISSA), 2016)We study a singlet scalar extension of the Standard Model. The singlet scalar is coupled non-minimally to gravity and assumed to drive inflation, and also couple sufficiently strongly with the SM Higgs field in order to ... -
Baryogenesis and gravity waves from a UV-completed electroweak phase transition
Laurent, Benoit; Cline, James M.; Friedlander, Avi; He, Dong-Ming; Kainulainen, Kimmo; Tucker-Smith, David (American Physical Society (APS), 2021)We study gravity wave production and baryogenesis at the electroweak phase transition in a real singlet scalar extension of the Standard Model, including vectorlike top partners, to generate the CP violation needed for ... -

Euclid preparation : XIX. Impact of magnification on photometric galaxy clustering
Euclid Collaboration (EDP Sciences, 2022)Aims. We investigate the importance of lensing magnification for estimates of galaxy clustering and its cross-correlation with shear for the photometric sample of Euclid. Using updated specifications, we study the impact ... -
Muon-electron lepton-flavor-violating transitions : Shell-model calculations of transitions in 27Al
Kostensalo, Joel; Suhonen, Jouni; Civitarese, O. (American Physical Society, 2018)In this paper we present the results of large-scale shell-model calculations of muon-to-electron lepton-flavorviolating transitions for the case of the target nucleus 27Al. We extend the previous shell-model calculations, done ...
