We present a new unification of the electro-weak and gravitational interactions based on the joining the weak SU(2) gauge fields with the left handed part of the spacetime connection, into a single gauge field valued in the complexification of the local Lorentz group. Hence, the weak interactions emerge as the right handed chiral half of the space-time connection, which explains the chirality of the weak interaction. This is possible, because, as shown by Plebanski, Ashtekar, and others, the… 
Planck Scale Physics, Gravi-Weak Unification and the Higgs Inflation
Starting with a theory of the discrete space-time at the Planck scale, we developed a Gravi-Weak Unification (GWU) - a $Spin(4,4)$-invariant model unified gravity with weak $SU(2)$ gauge and Higgs
Higgs potential from extended Brans-Dicke theory and the time-evolution of the fundamental constants
Despite the enormous significance of the Higgs potential in the context of the Standard Model of electroweak interactions and in Grand Unified Theories, its ultimate origin is fundamentally unknown
Euclidean Twistor Unification
Taking Euclidean signature space-time with its local Spin(4) = SU(2)L× SU(2)R group of space-time symmetries as fundamental, one can consistently gauge the SU(2)R factor to get a chiral spin
GRAVITY AND MIRROR GRAVITY IN PLEBANSKI FORMULATION
We present several theories of four-dimensional gravity in the Plebanski formulation, in which the tetrads and the connections are the independent dynamical variables. We consider the relation
False Vacuum Higgs Inflation and the Graviweak Unification
In the present paper we develop a model of the Higgs inflation based on the non-minimal coupling of the Higgs boson to gravity predicted by Graviweak Unification. But later we get rid of the
Gravity and unification: a review
We review various classical unified theories of gravity and other interactions that have appeared in the literature, paying special attention to scenarios in which spacetime remains four-dimensional,
Self-dual formulation of gravity in topological M-theory
Inspired by the low wave-length limit of topological M-theory, which re-constructs the theory of $3+1$D gravity in the self-dual variables' formulation, and by the realization that in Loop Quantum
Enhanced color gauge invariance and a new di-photon state at the LHC
We propose to interpret the possible resonance seen in di-photons at the LHC at 750 Gev as a bound state of a new pair of heavy gluons associated with an enhanced color gauge invariance. These have a
Variational technique for gauge boson masses
In this work, a novel mechanism for spontaneous symmetry breaking is presented. This mechanism incorporates gravity in the generation of masses for gauge fields, showing that the Higgs mechanism can
A new duality between topological M-theory and loop quantum gravity
Inspired by the long wave-length limit of topological M-theory, which re-constructs the theory of $3+1$D gravity in the self-dual variables' formulation, we conjecture the existence of a duality

Spontaneous Symmetry Breaking and Gravity
Gravity is usually considered to be irrelevant as far as the physics of elementary particles is concerned and, in particular, in the context of the spontaneous symmetry breaking (SSB) mechanism. We
Standard model and gravity from spinors
It is shown how the Lorentz and standard-model gauge groups can be unified by using algebraic spinors of the standard four-dimensional Clifford algebra, in left–right symmetric fashion. This defines

TLDR
This work describes an approach in which GR becomes an SU(2) gauge theory and describes how matter can be coupled to gravity in this formulation and, in particular, how both the gravity and Yang–Mills arise as sectors of a general diffeomorphism-invariant gauge theory.
Unified theory of nonlinear electrodynamics and gravity
We describe a class of unified theories of electromagnetism and gravity. The Lagrangian is of the BF type, with a potential for the B field, the gauge group is U(2) (complexified). Given a choice of
Quantum gravity, torsion, parity violation, and all that
We discuss the issue of parity violation in quantum gravity. In particular, we study the coupling of fermionic degrees of freedom in the presence of torsion and the physical meaning of the Immirzi
Gravity-Yang-Mills-Higgs unification by enlarging the gauge group
We revisit an old idea that gravity can be unified with Yang-Mills theory by enlarging the gauge group of gravity formulated as gauge theory. Our starting point is an action that describes a
Effective metric Lagrangians from an underlying theory with two propagating degrees of freedom
We describe an infinite-parametric class of effective metric Lagrangians that arise from an underlying theory with two propagating degrees of freedom. The Lagrangians start with the Einstein-Hilbert
Chiral vacuum fluctuations in quantum gravity
In this paper we investigate cosmological tensor modes in terms of the Ashtekar variables of loop quantum gravity, for complex values of the Immirzi parameter. While, on-shell, the classical
Spontaneous lorentz breaking and massive gravity.
TLDR
Theories with an extra spin-two field coupled to gravity admit a massive phase with broken Lorentz symmetry, and the Newtonian potentials are in general modified, but they may be protected by a scale symmetry of the coupling term.
Isogravity: Toward an Electroweak and Gravitational Unification
