  15. 24. Chimera baryon spectrum in a Sp(4) lattice gauge theory
    Ho Hsiao (National Yang Ming Chiao Tung U)
    09/12/2022, 16:50

    Chimera baryons are exotic objects playing the role of top partner in top partial compositeness among composite Higgs models. In the Sp(4) gauge theory with two fundamental and three antisymmetric Dirac fermions, they are composed of two fundamental and one antisymmetric fermion constituents. We present our preliminary results of Λ: (J, R) = (1/2, 5), Σ: (J, R) = (1/2, 10) and Σ∗: (J, R) =...

  16. 25. Primordial Black Holes and Gravitational Waves from the Tachyonic Instability in Higgs-R^2 Inflation
    Dhong Yeon Cheong (Yonsei U.)
    09/12/2022, 17:05

    The running of the Higgs self coupling may lead to numerous phenomena in early universe cosmology. In this talk I introduce a scenario where the Higgs running induces turns in the trajectory passing a region with tachyonic mass, leading to a temporal tachyonic growth in the curvature power spectrum. This effect induced by the Higgs leaves phenomena in the form of primordial black holes and...

  17. 26. FIMP dark matter from a hidden effective supersymmetric theory
    Wanda Isnard (Yonsei U.)
    09/12/2022, 17:20

    In this study, we present a dark matter model relying on hidden supersymmetric sectors such that dark matter particles are decoupled from the SM. We will consider dark matter as massive bound states of gluons and gluinos called glueballs and gluinoballs. We will discuss the possibility to produce such dark matter particles with a freeze-in mechanism.

  18. 27. Cosmological PBH production during a 1st order PT
    TaeHun Kim (Seoul National U.)

  19. 33. Pseudo-Nambu-Goldstone inflation with twin waterfalls
    Adriana Guerrero Menkara (Chung Ang U.)
    09/12/2022, 17:50

    We consider a model for pseudo-Nambu-Goldstone inflation, in which twin waterfall fields ensure a graceful exit from inflation. Adding a Z_2 symmetry for the waterfall and the inflation fields ensures the flatness of the inflationary potential, protecting it from large quantum corrections from the waterfall couplings.
    We study the initial conditions required for successful inflation and...
