a New Einstein-Hilbert Action and a Superon-Graviton Model (sgm) of Nature
Abstract
A nonlinear supersymmetric (NLSUSY) Einstein-Hilbert (EH)-type new action for the unity of nature is obtained by performing Einstein gravity analogue geometrical arguments in high symmetry spacetime inspired by NLSUSY. The new action is unstable and breaks down spontaneously into the EH action with matter in ordinary Riemann spacetime. All elementary particles except the graviton are composed of the fundamental fermion "superon" (the Nambu-Goldstone (NG) fermion of NLSUSY) and regarded as the eigenstates of SO(10) super-Poincaré (SP) algebra, called the superon-graviton model (SGM) of nature. Some phenomenological implications for low energy particle physics and cosmology are discussed. The linearization of NLSUSY including N=1 SGM action is attempted explicitly to obtain the linear SUSY local field theory, which is equivalent and renormalizable.
