Quasi Yukawa Fixed Point due to Decoupling of SUSY Particles
Tatsuo Kobayashi, Yoshio Yamagishi
We study effects of SUSY particle decouplings on a quasi fixed point (QFP) of Yukawa coupling. From renormalization group analysis it is shown that if the SUSY breaking scale …
Chaotic Inflation based on an Abelian D-flat Direction
Daijiro Suematsu, Yoshio Yamagishi
We study the inflation due to the D-flat direction of an extra . This scenario is a hybrid of a right-handed sneutrino inflaton scenario and a gauge non-singlet inflaton scen…
Radiative Symmetry Breaking in a Supersymmetric Model with an Extra
Daijiro Suematsu, Yoshio Yamagishi
Radiative symmetry breaking is studied in a superstring-inspired supersymmetric model which is extended with a low energy extra symmetry. In this model the -problem is ra…
Neutron Electric Dipole Moment under Non-Universal Soft SUSY Breaking Terms
T. Kobayashi, M. Konmura, D. Suematsu +2
The electric dipole moment of the neutron (EDMN) is re-examined in a general framework of the soft supersymmetry breaking. We point out some features of the relation between the ED…
Non-universal Soft Scalar Masses in Superstring Theories
T. Kobayashi, D. Suematsu, K. Yamada +1
We study soft scalar masses comparing with gaugino masses in 4-dimensional string models. In general non-universal soft masses are derived in orbifold models. We give conditions on…
Gauge Coupling Unification due to Non-universal Soft Supersymmetry Breaking
T. Kobayashi, D. Suematsu, Y. Yamagishi
Gauge coupling unification is studied in the MSSM with non-universal soft supersymmetry breaking terms. If gaugino masses are sufficiently smaller than scalar soft masses and the s…
