Supersymmetry-Breaking Nonlinear Sigma Models
Takumi Imai, K. -I. Izawa, Yuichiro Nakai
We consider a novel class of constraints on chiral superfields to obtain supersymmetric nonlinear sigma models in four spacetime dimensions, which strictly combine the internal sym…
Higgs Portal to Visible Supersymmetry Breaking
K. -I. Izawa, Yuichiro Nakai, Takashi Shimomura
We propose a supersymmetric extension of the standard model whose Higgs sector induces a spontaneous supersymmetry breaking by itself. Unlike the minimal extension, the current Hig…
Studying Gaugino Mass in Semi-Direct Gauge Mediation
M. Ibe, Izawa K. -I., Y. Nakai
We study gaugino mass generation in the context of semi-direct gauge mediation models, where the messengers are charged under both the hidden sector and the standard model gauge gr…
Conformal Supersymmetry Breaking in Vector-like Gauge Theories
K. -I. Izawa, Fuminobu Takahashi, T. T. Yanagida +1
A new class of models of dynamical supersymmetry breaking is proposed. The models are based on SU(N_C) gauge theories with N_F(<N_C) flavors of quarks and singlets. Dynamically gen…
Runaway Dynamics and Supersymmetry Breaking
K. -I. Izawa, Fuminobu Takahashi, T. T. Yanagida +1
Supersymmetric SU(N_C) gauge theories possess runaway-type superpotentials for N_F < N_C, where N_F is the flavor number of massless quarks. We show that the runaway behavior can b…
Strongly Coupled Semi-Direct Mediation of Supersymmetry Breaking
M. Ibe, K. -I. Izawa, Y. Nakai
Strongly coupled semi-direct gauge mediation models of supersymmetry breaking through massive mediators with standard model charges are investigated by means of composite degrees o…
