  3. 6. Gauge and Goldstone bosons from Flavour Symmetries
    Lorenzo Calibbi (Nankai University)
    04/06/2026, 10:30

    This seminar discusses models of fermion masses and mixing based on continuous flavour symmetries, emphasizing the phenomenology of the corresponding gauge bosons and — in the global symmetry case — the (pseudo) Nambu-Goldstone bosons arising from spontaneous symmetry breaking. Beginning with a brief overview of the Froggatt-Nielsen U(1) case, I will then focus on a realistic U(2) model. I...

  6. 8. Flavor Physics and CP from Non-Invertible Selection Rules
    Hajime Otsuka (Kyushu University)
    04/06/2026, 14:00

    In this talk, I will discuss the application of non-invertible selection rules to flavor physics and CP, in which matter fields are labeled by conjugacy classes of a finite group rather than its irreducible representations. We show that this framework leads to novel texture structures in the Yukawa couplings of quarks and leptons that cannot be realized by conventional group-theoretic...

  8. 10. The Minimal Supersymmetric Standard Model with Non-Invertible Selection Rules
    Yoshihiro SHIGEKAMI (Tsung-Dao Lee Institute and School of Physics and Astronomy)
    04/06/2026, 16:00

    We investigate a framework of the Minimal Supersymmetric Standard Model (MSSM) in which the quark and lepton flavor structure and suppression of flavor-changing neutral currents (FCNCs) are governed by non-invertible selection rules. By implementing such non-group-like fusion rules for matter fields, arising from gauging the outer automorphism $Z_2$ of a discrete $Z_N$ symmetry, we obtain...

  12. 13. Axion dark matter from heavy quarks
    Mohammad Aghaie

    We propose simple scenarios where the observed dark matter abundance arises from decays and scatterings of heavy quarks through freeze-in of an axion-like particle with mass in the 10 keV − 1 MeV range. These models can be tested by future X-ray telescopes, and in some cases will be almost entirely probed by searches for two-body decays K → π + invis. at NA62. As a byproduct, we discuss the...
