SUSY Breaking from Exotic U(1)
We propose a mechanism that the soft supersymmetry breaking masses can be
induced from the dynamical rearrangement of local U(1) symmetry in a
five-dimensional model. The U(1) symmetry possesses several extraordinary
features. The eigenstates of U(1) do not equal to those of boundary conditions.
The U(1) charge of standard model particles does not equal to that of
superpartners. A large U(1) charge hierarchy among superpartners and a standard
model gauge singlet is necessary in order to obtain the masses of O(1)TeV.Comment: Based on talk given at the International Workshop on Grand Unified
Theories (GUT2012) held at Yukawa Institute for Theoretical Physics, Kyoto,
Japan, March 201
Split Multiplets, Coupling Unification and Extra Dimension
We study a gauge coupling unification scenario based on a non-supersymmetric
5-dimensional model. Through an orbifold compactification, we obtain the
Standard Model with split multiplets on a 4-dimensional wall, which is
compatible with a grand unification.Comment: 10 pages, latex, no figure
Topological Grand Unification
We propose a new grand unification scenario for ensuring proton stability and
triplet-doublet Higgs mass splitting with the help of topological symmetry and
dynamics.Comment: 9 pages, version to appear in PT
Cubic Matrix, Generalized Spin Algebra and Uncertainty Relation
We propose a generalization of spin algebra using three-index objects. There
is a possibility that a triple commutation relation among three-index objects
implies a kind of uncertainty relation among their expectation values.Comment: Latex, 13page
