Zee-Babu model in a non-holomorphic modular symmetry and modular stabilization
Tatsuo Kobayashi, Hiroshi Okada, Yuta Orikasa
We study a Zee-Babu neutrino model in a non-holomorphic modular symmetry, and we construct a model so that there are minimum free parameters (two complex parameters). We find…
Origin of CKM matrix and natural FCNC suppression in gauge-Higgs unification
Yutaka Hosotani, Shuichiro Funatsu, Hisaki Hatanaka +2
In the gauge-Higgs unification in the Randall-Sundrum warped space the mixing in the couplings in the quark sector is induced by masses of $SO(…
Resonant leptogenesis in minimal extensions of the Standard Model
Arindam Das, Yuta Orikasa
We investigate a general scenario where we introduce three generations of Standard Model (SM) singlet Right Handed Neutrinos (RHNs) to generate the light neutrino mass thr…
A radiative seesaw in a non-holomorphic modular flavor symmetry
Hiroshi Okada, Yuta Orikasa
We study a non-holomorphic modular flavor symmetry in which we analyze neutrino sector, dark matter, and lepton flavor violations. The active neutrino mass is generated via o…
Probing chiral and flavored from cosmic bursts through neutrino interactions
ShivaSankar K. A., Arindam Das, Gaetano Lambiase +2
The origin of tiny neutrino mass is an unsolved puzzle leading to a variety of phenomenological aspects beyond the Standard Model (BSM). We consider gauge extension of the S…
