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…
Fermion Multiplicities at the GUT Scale: A Statistical Study of Unification and Proton Decay
Akifumi Chitose, Ko Hirooka, Masahiro Ibe +1
We study the impact of multiple vector-like fermions in SU(5) grand unified theory (GUT). Threshold effects from extra fermions allow the observed gauge couplings to be consistentl…
A Closer Look at Constrained Instantons
Takafumi Aoki, Masahiro Ibe, Satoshi Shirai
Instantons play a crucial role in understanding non-perturbative dynamics in quantum field theories, including those with spontaneously broken gauge symmetries. In the broken phase…
