Can a minimal radiative seesaw explain the LZ 248 keV event?
Hiroshi Okada, Yoshihiro Shigekami, Jia-Jun Wu
We interpret the recently reported 248~keV nuclear recoil event in the LUX-ZEPLIN (LZ) experiment via inelastic dark matter scattering within the minimal Scotogenic model. A sub-Me…
Neutron Portal and Dark Matter-Baryon Coincidence: from UV Completion to Phenomenology
Sudhakantha Girmohanta, Yuichiro Nakai, Yoshihiro Shigekami +1
We present a dynamical solution to the dark matter-baryon coincidence problem based on the neutron portal operator connecting the visible and dark sector asymmetries. This framewor…
A Minimal Realization of Radiative Dirac Neutrino Masses via a Non-Invertible Fusion Rule
Takaaki Nomura, Hiroshi Okada, Yoshihiro Shigekami
We propose a minimal one-loop radiative framework for Dirac neutrino mass matrix. As a consequence, the Yukawa hierarchies among the SM fermions are alleviated, and radiative type-…
Two-loop rainbow neutrino masses in a non-invertible symmetry
Hiroshi Okada, Yoshihiro Shigekami
We propose two-loop rainbow type of the neutrino mass model via gauging of non-invertible symmetry in which we introduce three families of isospin doublet vector-li…
The Minimal Supersymmetric Standard Model with Non-Invertible Selection Rules
Yuichiro Nakai, Hajime Otsuka, Yoshihiro Shigekami +1
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 (F…
Radiative lepton model in a non-invertible fusion rule
Takaaki Nomura, Hiroshi Okada, Yoshihiro Shigekami
We propose a radiatively induced lepton mass model introducing a gauging fusion rule. In our framework, the charged-lepton mass matrix is generated at one-loop level vi…
