Journal ArticleDOI

Locally Supersymmetric Grand Unification

TL;DR: In this paper, a locally supersymmetric grand unification program is proposed which couples the $N=1$ supergravity multiplet to an arbitrary grand unified gauge group with any number of left-handed chiral multiplets and a gauge vector multiplet.
Journal ArticleDOI

The Spectral action principle

TL;DR: In this paper, a new action principle was proposed to be associated with a non-commutative space, where the universal formula for the spectral action is a spinor on the Hilbert space.
Journal ArticleDOI

Gravity and the standard model with neutrino mixing

TL;DR: In this paper, a unified theory based on non-commutative geometry for the standard model with neutrino mixing, minimally coupled to gravity, is presented, and the unification is based on the symplectic unitary group in Hilbert space and on the spectral action.
Journal ArticleDOI

Mimetic dark matter

TL;DR: In this article, the authors modify the theory of gravity, isolating the conformal degree of freedom in a covariant way by introducing a physical metric defined in terms of an auxiliary metric and a scalar field.
Book

Applied N=1 supergravity

TL;DR: A review of recent developments in the applications of N = 1 supergravity to the construction of unified models of elementary particle interactions is given in this article, where a general formulation of spontaneous symmetry breaking and the criteria for breaking of internal symmetry and of local supersymmetry are described.
