Boson Mass and Grand Unification via the Type- Seesaw-like Mechanism
Yusuke Shimizu, Shonosuke Takeshita
We propose an SU(5) GUT model extended with two additional pairs of representation vector-like fermions. The CDF collaboration boson mass anomaly is explained by…
Mass Relations, Unification, and Proton Decay in the Mirror GUT Model
Yusuke Shimizu, Shonosuke Takeshita
We propose an SU(5)U(1)U(1) model without SUSY because the SUSY particles have not been observed yet. The gauge symmetry i…
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…
Renormalization group effects for a rank degenerate Yukawa matrix and the fate of the massless neutrino
Nicholas J. Benoit, Takuya Morozumi, Yusuke Shimizu +2
The Type-I seesaw model is a common extension to the Standard Model that describes neutrino masses. The Type-I seesaw introduces heavy right-handed neutrinos with Majorana mass tha…
Non-SUSY Lepton Flavor Model with 3HDM
Yukimura Izawa, Yusuke Shimizu, Hironori Takei
We propose a simple non-supersymmetric lepton flavor model with symmetry. The group is a minimal one which includes triplet irreducible representation. We introduce thr…
