Abstract: We find that there is no supersymmetric flavor-CP problem, mu-problem,cosmological moduli-gravitino problem or dimension four-five proton decayproblem in a class of supersymmetric theories with O(1) GeV gravitino mass. Thecosmic abundance of the non-thermally produced gravitinos naturally explainsthe dark matter component of the universe. A mild hierarchy between the massscale of supersymmetric particles and electroweak scale is predicted,consistent with the null result of a search for the Higgs boson at the LEP-IIexperiments. A relation to the strong CP problem is addressed. We propose aparametrization of the model for the purpose of collider studies. The scalartau lepton is the next to lightest supersymmetric particle in a theoreticallyfavored region of the parameter space. The lifetime of the scalar tau is ofO(1000) seconds with which it is regarded as a charged stable particle incollider experiments. We discuss characteristic signatures and a strategy forconfirmation of this class of theories at the LHC experiments.
