New Einstein-Hilbert-type Action and Superon-Graviton Model(SGM) of Nature

TL;DR

This paper introduces a novel nonlinear supersymmetric Einstein-Hilbert-type action inspired by NLSUSY, proposing a superon-graviton model where elementary particles are composed of fundamental fermions, with implications for particle physics and cosmology.

Contribution

It presents a new NLSUSY-inspired gravitational action and develops the superon-graviton model, linking elementary particles to fundamental fermions within a unified framework.

Findings

The new action is unstable and spontaneously breaks down into Einstein-Hilbert action with matter.

Elementary particles are modeled as eigenstates of SO(10) super-Poincaré algebra, composed of superons.

Linearization of NLSUSY leads to a renormalizable local field theory.

Abstract

A nonlinear supersymmetric(NLSUSY) Einstein-Hilbert(EH)-type new action for unity of nature is obtained by performing the Einstein gravity analogue geomtrical arguments in high symmetry spacetime inspired by NLSUSY. The new action is unstable and breaks down spontaneously into E-H action with matter in ordinary Riemann spacetime. All elementary particles except graviton are composed of the fundamental fermion "superon" of Nambu-Goldstone(NG) fermion of NLSUSY and regarded as the eigenstates of SO(10) super-Poincar\'e (SP) algebra, called superon-graviton model(SGM) of nature. Some phenomenological implications for the low energy particle physics and the 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.
