Nonanomalous R-symmetry in supersymmetric unified theories of quarks and leptons
Kiichi Kurosawa, Nobuhito Maru, T. Yanagida
A discrete R-symmetry often appears as an exact gauge symmetry in the low energy effective theory of superstring theories. We search for such discrete R-symmetries from a phenomeno…
Natural Effective Supersymmetry
Junji Hisano, Kiichi Kurosawa, Yasunori Nomura
Much heavier sfermions of the first-two generations than the other superparticles provide a natural explanation for the flavor and CP problems in the supersymmetric standard model…
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…
Large Squark and Slepton Masses for the First-Two Generations in the Anomalous U(1) SUSY Breaking Models
J. Hisano, Kiichi Kurosawa, Yasunori Nomura
Considering that the soft SUSY breaking scalar masses come from a vacuum expectation value of the D-term for an external gauge multiplet, the renormalization of the scalar masses i…
