A Clifford Algebra Realization of Supersymmetry and Its Polyvector Extension in Clifford Spaces

Authors: Carlos Castro
Comments: 15 pages, submitted to Foundations of Physics.

It is shown explicitly how to construct a novel (to our knowledge) realization of the Poincare superalgebra in 2D. These results can be extended to other dimensions and to (extended) superconformal and (anti) de Sitter superalgebras. There is a fundamental difference between the findings of this work with the other approaches to Supersymmetry (over the past four decades) using Grassmannian calculus and which is based on anti-commuting numbers. We provide an algebraic realization of the anticommutators and commutators of the 2D super-Poincare algebra in terms of the generators of the tensor product Cl1,1(R) x A of a two-dim Clifford algebra and an internal algebra A whose generators can be represented in terms of powers of a 3 x 3 matrix Q, such that Q3 = 0. Our realization differs from the standard realization of superalgebras in terms of differential operators in Superspace involving Grassmannian (anticommuting) coordinates θα and bosonic coordinates xμ. We conclude in the final section with an analysis of how to construct Polyvector-valued extensions of supersymmetry in Clifford Spaces involving spinor-tensorial supercharge generators Qμ1μ2.....μn and momentum polyvectors Pμ1μ2....μn. Clifford-Superspace is an extension of Clifford-space and whose symmetry transformations are generalized polyvector-valued supersymmetries.

A More Natural Reference Model Integrating Relativity and Quantum Mechanics

Authors: J Gregory Moxness
Comments: 28 pages, 1 figure, Latex. Original ideas from 1997, latest modifications Nov 22, 2007.

M Theory and/or Loop Quantum Gravity hold the promise of resolving the conflict between general relativity and quantum mechanics but lack experimental connections to predictability in physics. A connection is made to these and other theories vying for the title of a "Theory of Everything" by questioning the value of the traditional Planck unit reference point for the scales at which they operate. It also suggests a cosmological model which has acceleration as being fundamental. It provides for an intuitive understanding of the Standard Model and its relationship to particle masses and the structure of the atom. The prediction of particle mass and lifetimes is a good indicator for its validity.

No-Time-Dilation Corrected Supernovae 1a and GRBs Data and Low-Energy Quantum Gravity

Authors: Michael A. Ivanov
Comments: 5 pages, 2 figures, Latex. Poster contribution to the VI Int. Workshop on the Dark side of the Universe (DSU2010), Guanajuato U., Leon, Mexico, 1-6 June, 2010.

Earlier it was shown that in the model of low-energy quantum gravity by the author, observations of Supernovae 1a and GRBs, which are corrected by observers for characteristic for the standard cosmological model time dilation, may be fitted with the theoretical luminosity distance curve only up to z ~ 0:5; for higher redshifts the predicted luminosity distance is essentially bigger. The model itself has not time dilation due to another redshift mechanism. It is shown here that a correction of observations for no time dilation leads to a good accordance of observations and theoretical predictions for all achieved redshifts.

Hypothesis on Matter

Authors: Nainan K. Varghese
Comments: 14 pages

'Hypothesis on MATTER' is a revolutionary new concept, which explains all physical phenomena based on just one type of (postulated) basic particle - the Quantum of matter. Conception and development of this model is founded on the conviction that there can be only one type of basic entities. They provide substance and create all other real entities in nature. All (apparent) interactions and diverse properties of superior entities are logical developments from inherent properties of the (postulated) quanta of matter. Quanta of matter, by their natural interactions, creates and structure all other entities including an allencompassing medium. A wide array of physical phenomena are explained in the book [1]; from the origin of 3D matter to gravity and subatomic interactions to cosmological events, based on the simple mechanical interactions of quanta of matter. There is no more any need to envisage 'actions at a distance' or to invoke irrational assumptions like diversity of natural forces, mass-energy equivalence, duality of light or constancy of its speed, dual nature of electric charge, singularities, big bang, etc. This new concept will radically alter our understanding of the physical universe and at the same time, explain complex physical phenomena with simple 'Cause and Effect' relationships.

Spacetime Deformations Theory

Authors: Jacek Safuta
Comments: 11 pages

The spacetime deformations concept proposes a road to unification of general relativity and quantum mechanics i.e. unifies all interactions, answers the questions: why particles have mass and what they are, answers the question: what is energy and dark energy, unifies force fields and matter, implies new theories like the spacetime deformations evolution. I propose a new definition of matter and energy however not contradictory to current theories but totally contradictory to everyday experience. The new quality here is that the definition is supposed to be free of human being's perception and as far as possible also free of our language and culture limitations. I present also some points of view on computability of the actual Universe. This is a concept of principle (an universal concept delivering a description of nature) and not constructive one (describing a particular phenomenon using specific equations). The concept is background independent (the space has no fixed geometry).
