Inflation from periodic extra dimensions
Tetsutaro Higaki, Yoshiyuki Tatsuta
We discuss a realization of a small field inflation based on string inspired supergravities. In theories accompanying extra dimensions, compactification of them with small radii is…
Supersymmetric models on magnetized orbifolds with flux-induced Fayet-Iliopoulos terms
Hiroyuki Abe, Tatsuo Kobayashi, Keigo Sumita +1
We study supersymmetric (SUSY) models derived from the ten-dimensional SUSY Yang- Mills theory compactified on magnetized orbifolds, with nonvanishing Fayet-Iliopoulos (FI) terms i…
CP-violating phase on magnetized toroidal orbifolds
Tatsuo Kobayashi, Kenji Nishiwaki, Yoshiyuki Tatsuta
We study the CP-violating phase of the quark sector in the flavor model on with non-vanishing magnetic fluxes, where properties of possible origins…
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…
Comprehensive Analysis of Yukawa Hierarchies on with Magnetic Fluxes
Yukihiro Fujimoto, Tatsuo Kobayashi, Kenji Nishiwaki +2
Based on the result of classification in our previous work, we exhaustively investigate Yukawa sector of model on magnetized orbifolds , , $T^{2}/Z…
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…
