Determination of Majorana type-phases from the time evolution of lepton numbers
Nicholas J. Benoit, Yuta Kawamura, Saki Hamada +3
We have investigated an approach for determining the Majorana type-phases using the time evolution of lepton family numbers. We show how the second-order time derivative of the exp…
Effective theory for universal seesaw model and FCNC
Takuya Morozumi, Apriadi Salim Adam, Yuta Kawamura +3
We study the quark sector of the universal seesaw model with SU(2) SU(2) .The model incorporates the seesaw mechanism with the vector-like quarks (V…
Generalized Matter Parities from Finite Modular Symmetries
Tatsuo Kobayashi, Satsuki Nishimura, Hajime Otsuka +2
We classify a supersymmetric extension of the Standard Model by discrete symmetries originating from finite modular symmetries . Since all the couplings in supersymmetric theo…
Lepton flavor violation, lepton and electron EDM in the modular symmetry
Tatsuo Kobayashi, Hajime Otsuka, Morimitsu Tanimoto +1
We study the lepton flavor violation (LFV), the leptonic magnetic moments and the electric dipole moment (EDM) of the electron in the Standard-Model Effective Fiel…
Nonlinear magnon polaritons
Oscar Lee, Kei Yamamoto, Maki Umeda +6
We experimentally and theoretically demonstrate that nonlinear spin-wave interactions suppress the hybrid magnon-photon quasiparticle or "magnon polariton" in microwave spectra of…
New Physics Searches at Kaon and Hyperon Factories
Evgueni Goudzovski, Diego Redigolo, Kohsaku Tobioka +61
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths…
4D modular flavor symmetric models inspired by higher dimensional theory
Shota Kikuchi, Tatsuo Kobayashi, Hajime Otsuka +3
We study a scenario to derive four-dimensional modular flavor symmetric models from higher dimensional theory by assuming the compactification consistent with the modular symmetry.…
