Heavy Pseudo-Dirac Doublet Dark Matter and Non-Thermal Leptogenesis in Light of the LZ Event
Masahiro Ibe, Jun Miyamoto
Motivated by the recent LZ candidate nuclear-recoil event, we study pseudo-Dirac electroweak doublet dark matter in the mass range --, where bounds from s…

Radiative Breaking of Two-Zero Neutrino Mass Minors: Revisiting the Model
Masahiro Ibe, Jun Miyamoto, Satoshi Shirai
The two-zero minor structure predicted by flavor symmetries is usually discussed as a tree-level relation among low-energy neutrino parameters. We point out that this relation can…

Complete one-loop QED corrections to leptonic decays and impact on the CKM unitarity test
Teppei Kitahara, Jun Miyamoto, Kota Sasaki
Recently, a violation of the CKM unitarity condition has been reported in the latest charm-meson data and the latest lattice results, once the universal electroweak correction is t…
