A Model of Preons with Short Distance Scalar Interaction

Authors: Risto Raitio
Comments: 9 Pages. References added, discussion clarified.

A preon model is proposed based on spin 1/2 fermion and spin 0 boson constituents. They interact via a massive scalar field which is tentatively considered a phenomenological model of quantum gravity. Implications to generations, heavy boson states and dark matter are briefly discussed.

A Model of Space-time as an 11-dimensional State of Matter

Authors: Gary R. Heen
Comments: 24 Pages.

The model of this paper states that space-time is another state of matter, and that matter and space-time are composed of identical quantized physical units whose constituent sub-structures are composed of D-branes and Type I strings. The quantum structure of space-time and matter is designated the D-string. The D-strings of matter and space-time differ from one another only in the volumetric state of the D-string. The D-string model presupposes that the universe is composed solely of a finite number of D-stings with physical properties that are quantized with finite limits of range, and are responsible for all physical phenomena. The relationship of the D-string to Planck’s natural constants, gravity, time dilation, and the observed constancy of the speed of light are specifically addressed; a mathematical argument is presented demonstrating the conversion of space-time into matter.

Supersymmetry, Extra Dimensions, RG Running of the Higgs Quartic Coupling of MSSM/ NMSSM Models and the Seven Faces of the God Particle

Authors: A .Garcés Doz
Comments: 35 Pages. Minor bug fixes.

In this paper, we focus on the calculation of the supersymmetric term for obtaining the mass of the lightest Higgs boson. Thus will provide the scale of supersymmetry. Similarly, entering the exact angle β, ,will allow us to calculate the masses of the remaining four Higgs bosons , mA , mH0 , mH ± and the stop mass 422.9 Gev. Was used for this, the well-known model of a one-dimensional string, or a dimensional box. We believe that the results obtained consistent with the observation, carry a string model mathematically satisfactory of a n-dimensional string, well known to all physicists. The main novelty of this model is the introduction of dimensionless ratios between the Planck length and the length n dimensional, as the length of the string. An extension of the Heisenberg principle to extra dimensions, will derive a principle of equivalence between mass, time and space so that it showed that the mass is actually another dimension. This principle of equivalence, so described, anger further and allow the equivalence between spin, probability, fluctuations and dimensions. Successive breaking symmetries-topology geometry involved, appears to be the cause of the distinguishability between spins, number of particles, dimensions, etc.; to the observer

Energy and Spacetime

Authors: Ryoji Furui
Comments: 6 Pages.

A modified framework for special relativity is proposed in which mass is incorporated in the temporal components of the Minkowski metric and a particle may convert between massive and massless states. The speed of such a particle therefore changes between subluminal and luminal. The well-known equations for relativistic energy of massive and massless particles do not conflict with the notion that a massive particle can convert all of its mass into energy, thereby removing the problem of requiring infinite energy to reach the speed of light barrier. This enables the production of gravitons, which in collisions transfer their momentum and energy to matter, thereby giving rise to the gravitational force. The conversion of particles between massive and massless states suggests that time, and hence the universe, is eternal.

If a Machian Relationship Between Gravitons and Gravitinos Exist, What Does Such a Relationship Imply as to Scale Factor, and Quinessence Evolution?

Authors: A.W.Beckwith
Comments: 9 pages, completely re did the last 3 pages. Document completely re focused after criticism by GRG journal editors

The Mach’s principle as unveiled in this paper is really a statement as to information conservation, with Gravitons and Gravitinos being information carriers. What we wish to know is are there measurable consequences as far as scale factor evolution, spatial distance expansion and cosmological density proportional to a quinessent variant of the cosmological ‘constant’ parameter ?

Progress in Clifford Space Gravity

Authors: Carlos Castro
Comments: 22 Pages. Submitted to Advances in Applied Clifford Algebras

Clifford-space Gravity is revisited and new results are found. The Clifford space ($ C$-space) generalized gravitational field equations are obtained from a variational principle and which is based on an extension of the Einstein-Hilbert-Cartan action. One of the main results of this work is that the $C$-space connection requires torsion in order to have consistency between the Clifford algebraic structure and the zero nonmetricity condition $ \nabla_K g^{MN} = 0 $. A discussion on the cosmological constant and bi-metric theories of gravity follows. We continue by pointing out the relations of Clifford space gravity to Lanczos-Lovelock-Cartan (LLC) higher curvature gravity with torsion. We finalize by pointing out that $ C$-space gravity involves higher-spins beyond spin $ 2 $ and argue why one could view the LLC higher curvature actions, and other extended gravitational theories based on $ f ( R ), f ( R_{\mu \nu} ), ... $ actions, for polynomial-valued functions, as mere $effective$ actions after integrating the $C$-space gravitational action with respect to all the poly-coordinates, except the vectorial ones $ x^\mu$.

The Unified Field Theory: Synopsis of a Personal Quest

Authors: John A. Gowan
Comments: 10 Pages.

Most of my effort has been expended on bringing gravitation into the fold with the other forces, and on the details of the weak force mechanism. I think I have been successful in both these areas. However, I only claim a conceptual qualitative unification, not a mathematical quantitative unification. I have tried to understand unification from the perspective of the most general physical conservation laws and inclusive principles (I have especially used General Systems ideas regarding fractal patterns in nature).

Gravity Probe B and the Rañada-Milgrom Effect

Authors: David Brown
Comments: 5 Pages.

Gravity Probe B (GP-B) is a space mission which used a satellite with 4 super-accurate gyroscopes to test the frame-dragging effect predicted by general relativity theory. The satellite was launched on April 20, 2004, and the spaceflight phase of the mission lasted until 2005. The GP-B science team alleges that highly predictable and systematic malfunctions in the gyroscopes created signal noise, and when the signal noise is removed from the empirical data, then Gravity Probe B confirms the precise frame-dragging effect predicted by general relativity theory without the Rañada-Milgrom effect. However, if the gyroscopes functioned within design specification, then the alleged defects in the gyroscopes might be confirmations of the Rañada-Milgrom effect.

On a New Position Space Doubly Special Relativity Theory

Authors: Golden Gadzirayi Nyambuya
Comments: 14 Pages. To be submitted to a peer review journal

he general consensus feeling amongst researchers is that it is generally difficult to obtain a position space Lorentz invariant Doubly Special Relativity (DSR) theory. In this reading, we propose such a theory. The Lorentz transformations are modified such that the resultant theory has not one, but two invariants -- the speed of light c = 2.99792458e 8 m/s, and a minimum length. Actually, we achieve our desire by infusing Heisenberg's quantum mechanical uncertainty principle into the fabric of Minkowiski spacetime. In this new theory, it is seen that under extreme quantum conditions, it should be possible to exceed the light-speed-barrier without any limit. It should be stated that this theory has been developed more as a mathematical exercise to obtain a physically reasonable as is possible a position space DSR theory that is Lorentz invariant. In the low energy regime, the theory gives the same predictions as Einstein's Special Theory of Relativity (STR).

Is a Non Zero “LOWER” Order Graviton Mass Derivable in Brane Theory Settings and Kaluza Klein Graviton Models?

Authors: A.W. Beckwith
Comments: 8 pages. Extensively re done due to criticism of an editor in classical and quantum gravity

The lowest order mass for a KK graviton, as a non zero product of two branes interacting via a situation similar to Steinhardt’s ekpyrotic universe is obtained, as to an alternative to the present dogma specifying that gravitons must be massless. The relative positions as to the branes gives a dynamical picture as to how lowest order KK gravitons could be affected by contraction and then subsequent expansion. And the solution picked is for with a non zero lowest order mass for a KK graviton permits modeling of gravitons via a dynamical Casmir effect which we generalize using Durrer’s 2007 work. Anti-de-Sitter braneworld.construction is what is used to model the Casmir effect. This analysis is taken in AdS5 geometry while assuming that blue spectrum treatment of gravitons no longer holds.

Everything: What is It?

Authors: Constantine Tynyansky
Comments: 141 Pages.

This is a slide show version of the Conceptual Physics, which studies the concept of nonmathematical EVERYTHING. The way to introduce the concept of EVERYTHING requires other – is not based on neglect, that is nonmathematical consideration. Such comprehensive consideration is not arbitrary – does not allowing variants (models). It is obvious that the production of popular versions of theoretical modeling with the requirement to identify the "correct" for the comparison with observation (certainly not inclusive) and/or aesthetic criteria (rather arbitrary) is not a comprehensive consideration. In other words, the "correctness" that, understands what is seen cannot be obtained in the examination, but needed some additional actions. Thus, a comprehensive consideration (Conceptual Physics) cannot be other, as well as what considered is seen – EVERYTHING. RUSSIAN Это слайд-шоу версия Концептуальной физики, которая изучает нематематическое понятие ВСЁ. То, как ввести в рассмотрение понятие ВСЁ, требует иного – не основанного на пренебрежении, то есть нематематического рассмотрения. Такое, всеобъемлющее рассмотрение оказывается непроизвольным – не допускающим варианты (модели). Очевидно, что популярное производство вариантов теоретического моделирования с требованием выявления «правильного» по сопоставлению с наблюдением (заведомо не всеохватным) и/или эстетическим критериям (достаточно произвольным) не является всеобъемлющим рассмотрением. Иначе говоря, «правильность», то есть понимание того, что рассматривается, не может быть получена в самом рассмотрении, а нуждается в каких-то дополнительных действиях. Таким образом, всеобъемлющее рассмотрение (Концептуальная физика) не может быть иным, как и то, что рассматривается – ВСЁ.
