On structure of superon-graviton model(SGM)

The fundamental action of superon-graviton model(SGM) for space-time and matter is written down explicitly in terms of the fields of the graviton and superons by using the affine and the spin connection formalisms, alternatively. Some characteristic structures including some hidden symmetries of the gravitational coupling of superons are manifested (in two dimensional space-time) with some details of the calculations. SGM cosmology is discussed briefly.

New supersymmetry algebra on gravitational interaction of Nambu-Goldstone fermion

The spacetime symmetries of SGM action proposed as the gravitational coupling of N-G fermions are investigated. The commutators of new nonlinear supersymmetry (NL SUSY) transformations form a closed algebra, which reveals N-G fermion (NL SUSY) nature and a generalized general coordinate transformation. A generalized local Lorentz transformation, which forms a closed algebra, is also introduced.

Supersymmetric structure of spacetime and matter -superon-graviton model-

A unified description of spacetime and matter is proposed by using a single irreducible representation of SO(10) Super-Poincare algebra(SO(10)SPA). All (observed) elementary particles except the graviton are the (massless) eigenstates of SO10)SPA composed of fundamental Nambu-Goldstone fermions with spin 1/2, superons, associating with the spontaneous breakdown of the supertranslation of the spacetime. The systematic investigations of the standard model(SM) and SU(5)GUT by using superon diagrams may reveal the generation structure, the stability of the proton, K-, B-, D- mixings, CP-violation, the atmospheric and solar neutrino deficits and the absence of the electroweak lepton-flavor-mixing. The fundamental action of the superon-graviton model(SGM) for spacetime and matter is proposed, which is invariant under a new supersymmetry.

Supersymmetric Structure of Spacetime and Matter -Superon Quintet Hypothesis-

A unified description of spacetime and matter at the Planck scale is proposed by using the irreducible representation of N=10 extended Super-Poincaré algebra, where all matters and all forces except the graviton are the supersymmetric composites made of the fundamental objects with spin 1/2, superon quintet. All the local gauge interactions in GUTs are investigated systematically by using the superon diagrams. The proton is stable and the flavor changing neutral current process is suppressed in the superon pictures of GUTs. The fundamental action of the superon model is proposed. The characteristic predictions which can be tested in the (coming) high energy experiments are discussed briefly.
