The Standard Model of Elementary Particle Physics has global Family flavor symmetries corresponding to the 3 families in the Standard Model. It has been shown that the breaking of these symmetries at low energy produces Dark Energy which is the dominant component of the energy density of the Universe. It has also been shown that this model of Dark Energy not only explains the accelerated expansion of the universe but has additional observational consequences and makes verifiable predictions. This model allows a space-time dependent Dark Energy as indicated by recent observations. Further, the collapse of space dependent Dark Energy configurations leads to the formation of Dark Energy Black Holes resulting in verifiable predictions. We examine the implications of these symmetries at high energies and in the Early Universe. We consider what might happen if these global symmetries get gauged and that the global symmetries today are just a consequence of the gauge fields acquiring a constant vacuum expectation value below some energy scale v. Since, we have not yet seen signatures of such gauge fields at any of our particle accelerators, this would imply that v is greater than the electroweak scale. In the early Universe, when these gauge fields would be dynamical, the Higgs would not yet have acquired a non-zero vacuum expectation value and all Standard Model particles would be massless. The gauging of these global symmetries is desirable from a high energy and quantum gravity perspective. The chiral dynamics has a natural interpretation in terms of D Branes and our 4-dimensional Universe embedded in higher dimensions. Anomaly cancellation in this scenario results from the sum of the cubic terms vanishing. Finally, the analysis in this article can provide an explanation for one of the long standing mysteries of the natural world: the matter - antimatter asymmetry observed in our Universe.

We investigate non-gravitational signals of dark energy within the framework of gauge symmetry in the dark energy sector. Traditionally, dark energy has been primarily studied through gravitational effects within general relativity or its extensions. On the other hand, the gauge principles have played a central role in the standard model sector and dark matter sector. If the dark energy field operates under a gauge symmetry, it introduces the possibility of studying all major...

Two theoretically well-motivated gauge extensions of the standard model are $SU(3)_C \times SU(3)_L \times SU(3)_R$ and $SU(3)_q \times SU(3)_L \times SU(3)_l \times SU(3)_R$, where $SU(3)_q$ is the same as $SU(3)_C$ and $SU(3)_l$ is its color leptonic counterpart. Each as three variations, according to how $SU(3)_R$ is broken. It is shown here for the first time that a built-in dark $U(1)_D$ gauge symmetry exists in all six versions, and may be broken to discrete $Z_2$ dark ...

Non-Abelian family symmetries offer a very promising explanation for the flavour structure in the Standard Model and its extensions. We explore the possibility that dark matter consists in fermions that transform under a family symmetry, such that the visible and dark sector are linked by the familons - Standard Model gauge singlet scalars, responsible for spontaneously breaking the family symmetry. We study three representative models with non-Abelian family symmetries that ...

We propose a geometric explanation of the standard model of Glashow, Weinberg and Salam for the known elementary particles. Our model is a generic Quantum Field Theory in dimension four, obtained by developing along a Lorentz sub-manifold the lagrangian of Einstein and Dirac in dimension twelve. The main mechanism which gives birth to the standard model is a certain gauge fixing of triality, which permits to identify the multiplicity of fermions, as seen from the four dimensi...

This theoretical particle physics thesis is an investigation into old and new symmetries of Nature. Known symmetries and conservation laws serve as a guide for dark and visible sector model building. New symmetries of Nature are proposed, broken and subsequently reinstated at high temperatures in order to discover well-motivated particle physics models for cosmological observations implying the existence of a dark sector. Candidate processes for creation of a non-primordial m...

We propose an extension of the Standard Model in which baryon number is promoted to be part of a non-Abelian gauge symmetry at high energies. Specifically, we consider the gauge group SU(4) x SU(2)_L x U(1)_X, where the SU(4) unifies baryon number and color. This symmetry is spontaneously broken down to the Standard Model gauge group at a scale which can be as low as a few TeV. The SU(4) structure implies that each SM quark comes along with an uncolored quark partner, the lig...

We generalize the standard model of particle physics such it displays global scale invariance. The gravitational action is also suitably modified such that it respects this symmetry. This model is interesting since the cosmological constant term is absent in the action. We find that the scale symmetry is broken by the recently introduced cosmological symmetry breaking mechanism. This simultaneously generates all the dimensionful parameters such as the Newton's gravitational c...

The spin-charge-family theory, which is a kind of the Kaluza-Klein theories in $d=(13+1)$ --- but with the two kinds of the spin connection fields, the gauge fields of the two Clifford algebra objects, $S^{ab}$ and $\tilde{S}^{ab}$ --- explains all the assumptions of the standard model: The origin of the charges of fermions appearing in one family, the origin and properties of the vector gauge fields of these charges, the origin and properties of the families of fermions, the...

More than 40 years ago the standard model made a successful new step in understanding properties of fermion and boson fields. Now the next step is needed, which would explain what the standard model and the cosmological models just assume: a. The origin of quantum numbers of massless one family members. b. The origin of families. c. The origin of the vector gauge fields. d. The origin of the Higgses and Yukawa couplings. e. The origin of the dark matter. f. The origin of the ...

We introduce a new class of $U(1)_X$ symmetries where all Standard Model fermions are "chiral", i.e. the left and right-handed components have different charges under the $U(1)_X$ symmetry. Gauge anomaly cancellation is achieved by introducing three Standard Model gauge singlet dark fermions ($f^i$; $i=1,2,3$) charged under this symmetry. We systematically present chiral solutions for cases in which (a) one, (b) two, or (c) all three generations of Standard Model fermions are...
