Flavor Changing Neutral Higgs Bosons in a Supersymmetric Extension based on a Family Symmetry
Naoko Kifune, Jisuke Kubo, Alexander Lenz
A supersymmetric extension of the standard model based on the discrete family symmetry is considered, and we investigate flavor-changing neutral current (FCNC) processes, esp…
Discrete R-symmetry anomalies in heterotic orbifold models
Takeshi Araki, Kang-Sin Choi, Tatsuo Kobayashi +2
Anomalies of discrete R-symmetries appearing in heterotic orbifold models are studied. We find that the mixed anomalies for different gauge groups satisfy the universal Green-Schwa…
Double Suppression of FCNCs in a Supersymmetric Model
Y. Kajiyama
A concrete model which can suppress FCNCs and CP violating phenomena is suggested. It is an symmetric extension of the MSSM in extra dimensions, where only SU(2) and SU(3) ga…
Suppressing FCNC and CP-Violating Phases with Extra Dimensions
Jisuke Kubo, Haruhiko Terao
The infrared attractiveness of soft-supersymmetry breaking (SSB) parameters is investigated in extra dimensions. The SSB parameters are assumed to run from the Planck scale M_{PL}…
Running couplings in extra dimensions
Jisuke Kubo, Haruhiko Terao, George Zoupanos
The regularization scheme dependence of running couplings in extra compactified dimensions is discussed. We examine several regularization schemes explicitly in order to analyze th…
Applications of the Reduction of Couplings
Jisuke Kubo
Applications of the principle of reduction of couplings to the standard model and supersymmetric grand unified theories are reviewed. Phenomenological applications of renormalizati…
