Semi-direct Gauge Mediation in Conformal Windows of Vector-like Gauge Theories
T. T. Yanagida, Kazuya Yonekura
Direct gauge mediation models using the Intriligator-Seiberg-Shih (ISS) metastable vacua suffer from the Landau pole problem of the standard model gauge couplings and the existence…
Gauge Mediation with D-term SUSY Breaking
Y. Nakayama, Masato Taki, Taizan Watari +1
We construct a gauge-mediation model with a D-term supersymmetry (SUSY) breaking. R-symmetry breaking necessary for generating the SUSY standard-model gaugino masses is given by ga…
Super- and CP-symmetric QCD in Higher Dimensions
K. -I. Izawa, Taizan Watari, T. Yanagida
An extremely precise global symmetry is necessary in the Peccei--Quinn solution to the strong CP problem. Such symmetry arises when colored chiral fermions are localized in an inte…
Product-Group Unification in Type IIB String Thoery
Taizan Watari, T. Yanagida
The product-group unification is a model of unified theories, in which masslessness of the two Higgs doublets and absence of dimension-five proton decay are guaranteed by a symmetr…
Natural Gravitino Dark Matter and Thermal Leptogenesis in Gauge-Mediated Supersymmetry Breaking Models
Masaaki Fujii, T. Yanagida
We point out that there is no cosmological gravitino problem in a certain class of gauge-mediated supersymmetry-breaking (GMSB) models. The constant term in the superpotential natu…
Higher-Dimensional QCD without the Strong CP Problem
K. -I. Izawa, T. Watari, T. Yanagida
QCD in a five-dimensional sliced bulk with chiral extra-quarks on the boundaries is generically free from the strong CP problem. Accidental axial symmetry is naturally present exce…
