  1. 281. Hubble-induced phase transitions as a natural quintesential inflation reheating mechanism
    Dr JAVIER RUBIO (Universidad Complutense de Madrid)
    06/06/2024, 16:40

    A Hubble-induced phase transition is a natural spontaneous symmetry breaking mechanism allowing for explosive particle production in non-oscillatory models of inflation involving non-minimally coupled spectator fields. I will discuss the impact of this effect on the reheating of the Universe after inflation and its characterization via 3+1-dimensional classical lattice simulations, discussing...

  3. 219. Electroweak Symmetry Restoration in Extended Higgs Sectors via Domain Walls
    Mohamed Younes Sassi (2.Institute for theoretical Physics Hamburg)
    06/06/2024, 17:20

    Domain walls are a type of topological defects that can arise in the
    early universe after the spontaneous breaking of a discrete symmetry. This occurs in several beyond Standard Model theories with an
    extended Higgs sector such as the Next-to-Two-Higgs-Doublet model
    (N2HDM). In this talk I will discuss the domain wall solution related
    to the singlet scalar of the N2HDM as well as...

  4. 272. Precision Calculations of Effective Potentials and Electroweak Phase Transitions in the Early Universe
    Mr Andrii Dashko (DESY Theory)
    06/06/2024, 17:40

    We present a detailed study of the precision calculations of higher-order contributions to effective potential with the application of three-dimensional effective field theories (3D EFTs). Our work focuses on the thermodynamic quantification and description of electroweak phase transitions in the early Universe for the complex singlet extended Standard Model (cxSM). In particular, we address...

  5. 210. Electroweak phase transition in maximally symmetric composite Higgs model
    Dr Marco Merchand (KTH)

    In this paper we demonstrate that strong first order phase transitions can be realized within a maximally symmetric composite Higgs model featuring explicit CP violation. The maximal symmetry guarantees the finiteness of the radiatively generated potential for the pseudo-Nambu-Goldstone bosons, rendering the thermal evolution of the model fully calculable. We compute the finite temperature...
