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…
Breit-Wigner Enhancement of Dark Matter Annihilation
Masahiro Ibe, Hitoshi Murayama, T. T. Yanagida
We point out that annihilation of dark matter in the galactic halo can be enhanced relative to that in the early universe due to a Breit-Wigner tail, if the dark matter annihilates…
R-axion detection at LHC
Hock-Seng Goh, Masahiro Ibe
Supersymmetric models with spontaneously broken approximate R-symmetry contain a light spin 0 particle, the R-axion. The properties of the particle can be a powerful probe of the s…
Conformal Gauge Mediation and Light Gravitino of Mass m_{3/2} <O(10) eV
M. Ibe, Y. Nakayama, T. T. Yanagida
We discuss a class of gauge mediated supersymmetry breaking models with conformal invariance above the messenger mass scale (conformal gauge mediation). The spectrum of the supersy…
Conformal Supersymmetry Breaking and Dynamical Tuning of the Cosmological Constant
M. Ibe, Y. Nakayama, T. T. Yanagida
We propose "conformal supersymmetry breaking" models, which tightly relate the conformal breaking scale (i.e. R-symmetry breaking scale) and the supersymmetry breaking scale. The b…
