A classical cosmological model for triviality
The aim of this paper is to study the triviality of λφ theory in a classical gravitational model. Starting from a conformal invariant scalar tensor theory with a self-interaction term λφ, we investigate the effect of a conformal symmetry breaking emerging from the gravitational coupling of the large-scale distribution of matter in the universe. Taking in this cosmological symmetry breaking phas...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Quantum Cosmological Perfect Fluid Model and Its Classical Analogue
The quantization of gravity coupled to a perfect fluid model leads to a Schrödingerlike equation, where the matter variable plays the role of time. The wave function can be determined, in the flat case, for an arbitrary barotropic equation of state p = αρ; solutions can also be found for the radiative non-flat case. The wave packets are constructed, from which the expectation value for the scal...
متن کاملTriviality and the Standard Model
The triviality of the scalar sector of the standard one-doublet Higgs model implies that this model is only an effective low-energy theory valid below some cutoff scale Λ. We show that the experimental constraint on the amount of custodial symmetry violation implies that the scale Λ must be greater than of order 7.5 TeV. The underlying high-energy theory must also include flavor dynamics at a s...
متن کاملWeek 2: Classical Cosmological Tests
In the following, we will assume that the Universe consists of nonrelativistic matter and possibly a cosmological constant. Before proceeding, let us justify our neglect of radiation. A variety of measurements (including, for example, simply weighing galaxies and then measuring their space density) indicate a nonrelativistic-matter density ρm ≃ 0.3ρc ≃ 1.5× 10−6 GeV/cm3 (for h ≃ 0.7). We observ...
