A Test for Light Gravitino Scenario at the LHC
Satoshi Shirai, T. T. Yanagida
Supersymmetric (SUSY) standard models in which the lightest SUSY particle (LSP) is an ultralight gravitino (m_{3/2}=O(1) eV) are very attractive, since they are free from the cosmo…
R-violating Decay of Wino Dark Matter and electron/positron Excesses in the PAMELA/Fermi Experiments
Satoshi Shirai, Fuminobu Takahashi, T. T. Yanagida
We show that R-parity violating decay of Wino dark matter of mass \sim 3 TeV can naturally account for the flux and spectral shape of the cosmic-ray electrons and positrons observe…
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…
