CP violating phase from minimal texture neutrino mass matrix: Test of the phase relevant to leptogenesis
Masataka Fukugita, Yuya Kaneta, Yusuke Shimizu +2
The model of neutrino mass matrix with minimal texture is now tightly constrained by experiment so that it can yield a prediction for the phase of CP violation. This phase is predi…
Edge of a cliff
Yusuke Shimizu, Yoshiyuki Tatsuta
We discuss the neutrino flavor structures in the Occam's razor approach for the Dirac neutrino mass matrices. We assume that the charged lepton mass matrix takes a diagonal base, w…
Occam's Razor in Lepton Mass Matrices - The Sign of Universe's Baryon Asymmetry -
Yuya Kaneta, Yusuke Shimizu, Morimitsu Tanimoto +1
We discuss the neutrino mass matrix based on the Occam's Razor approach in the framework of the seesaw mechanism. We impose four zeros in the Dirac neutrino mass matrix, which give…
Model for the Lepton Flavor Structure and the Strong Problem
Takaaki Nomura, Yusuke Shimizu, Toshifumi Yamada
We present a model with lepton flavor symmetry which explains the origin of the lepton flavor structure and also solves the strong problem. Standard mod…
Double Froggatt--Nielsen Mechanism
Kenji Nishiwaki, Yusuke Shimizu, Yoshiyuki Tatsuta
We present a doubly parametric extension of the standard Froggatt--Nielsen (FN) mechanism. As is well known, mass matrices of the up- and down-type quark sectors and the charged le…
Mass Limit for Light Flavon with Residual Symmetry
Yu Muramatsu, Takaaki Nomura, Yusuke Shimizu
We present a modified Altarelli and Feruglio model where an additional singlet-prime flavon is introduced. In this model, non-zero is given by this additional…
