Description
MSSM and SUSY GUTs are the candidates
of theoretical models beyond SM.
However the naive extensions of SM allow many arbitrary parameters
and many unobserved elementary (SUSY) particles, which
lose simplicity of Nature and the predictive powers.
In this talk, firstly we review quickly the NLSUSYGR
which describes the NLSUSY invariant coupling of
(Nambu-Godldstone fermion) Volkov-Akulov model of
NLSUSY with Eistein general relativity
from the geometrical and algebraic viewpoints.
Secondly we show that in the assymptotic flat spacetime
the matter sector of NLSUSYGR is recasted as the familiar
linear SUSY model and give new insights into the origin of mass,
SUSY breaking scale, dark energy, neutrino mass, etc.
These may suggest the only N-fundamental objects (N Nambu-Goldstone
fermionｓ) as the ultimate objects for all (obsserved) particles
and forces except gravity. Gravity is accomodated as elementary.
