A Relation on Gaugino Masses in a Supersymmetric SO(10)_GUT x SO(6)_H Unified Model
Kiichi Kurosawa, Yasunori Nomura, Koshiro Suzuki
The doublet-triplet splitting problem in supersymmetric grand unified theories is elegantly solved in a supersymmetric SO(10)_GUT x SO(6)_H model. In this model, the gauginos in th…
Grand-Unification Scale Generation through the Anomalous U(1) Breaking
K. -I. Izawa, Kiichi Kurosawa, Yasunori Nomura +1
We discuss the anomalous U(1) gauge symmetry as a mechanism of generating the grand-unification scale. We conclude that unification to a simple group cannot be realized unless some…
Anomalous U(1) Gauge Symmetry and Lepton Flavor Violation
Kiichi Kurosawa, Nobuhiro Maekawa
In recent years, many people have studied the possibility that the anomalous U(1) gauge symmetry is a trigger of SUSY breaking and/or an origin of the fermion mass hierarchy. Thoug…
