Talk	Oral abstract	Title	General Relativity(GR) in Nonlinear Supersymmetric Space-time and Unity of Nature
Co-authors
Abstract	We extend Riemann space-time to degrees of freedom for nonlinear(NL) representation of SUSY, i.e. tangent space is specified by Grassmann coordinates \psi_{alpha} besides the Minkowski coordinates \x_{a}. Performing ordinary geometric arguments of GR we obtain NLSUSY invariant Einstein-Hilbert(EH) type action(NLSUSYGR) equipped with the cosmological term. We show that NLSUSYGR would induce the spontaneous spacetime SUSY breaking [superGL(4,R)/GL(4,R)] and that the cosmological term(NLSUSY action for Nambu-Goldstone fermion) reproduces in tangent space the familiar broken linear(L) SUSY model in the true vacuum, Various symmetries of the model, cosmological meanings and SUSY effects mediated to the low energy particle physics are discussed.
