Theoretical and experimental approaches to the dark energy and the cosmological constant problem.
The cosmological constant problem is one of the most pressing problems of physics at this time. In this dissertation the problem and a set of widely-discussed theoretical solutions to this problem are reviewed. It is shown that a recently developed Lorentz gauge theory of gravity can provide a …

Relevant Operators of Particle Physics and Cosmology
… is the Higgs mass which causes the "hierarchy problem", while the cosmological constant term of cosmology results in the "cosmological constant problem". In this thesis defense, I will discuss about how these issues can guide us in the pursuit of searching for new physics, both from a model …

Kaluza-Klein Theories, Branes and Cosmology
… of the singularities. In order to approach the Cosmological Constant Problem and the related dark energy discussion in this context, we study the cosmology of a toy model, six-dimensional Einstein-Maxwell theory. The time independence of the deficit angle branes is proven. Some special cases are …

Beyond Standard Model Physics under the ground and in the sky
… In this dissertation, we have explored some problems which are not addressed by the standard models of particle physics and cosmology. The implications of the Higgs discovery and lack of new physics results are far reaching. To better understand the nature of Higgs and its connections to …
