Q1.00001: A Map Between d = 3 and d = 4 Spacetime Dimensional k-strings Using Holography Xiaolong Liu, Kory Stiffler We investigate k-string in d=3 and d=4 spacetime dimensions using holography. Exploiting the similarities between two supergravity backgrounds,Maldacena-Nunez background and Maldacena-Nastase background, we map calculations for k-strings between d = 3 and d = 4 spacetime dimensions. The specific calculations investigated are the usual lowest order tension term for the energy of k-strings and the first order, one loop corrections, the Luscher term. The tension term is proportional to L, the length between quark antiquark pairs and the Luscher term is the typical 1/L Coulombic correction. [Preview Abstract] |

Q1.00002: Diffeomorphisms as a Source of the C.M.B. Anisotropy Christopher Doran, Kory Stiffler, Vincent Rodgers The diffeomorphism field is a rank-two tensor that naturally arises from the Virasoro algebra. It was suggested by Rodgers and Yasuda that this field has the potential as a candidate for the inflaton in the early universe and appears in the origins of dark energy in cosmology. We are now examining its influence on the C.M.B. anisotropy, which is one of cosmology's outstanding problems. We consider first-order space-time dependent fluctuations to the Einstein tensor through fluctuations to the metric, diffeomorphism field, and perfect fluid tensor for radiation. The goal is to find appropriate solutions and use them in the CMBFast or CAMB simulations to get a picture of the diffeomorphism field's contribution to the anisotropy. [Preview Abstract] |

Q1.00003: The capability of the ALICE detector to measure the production of b-quark contining hadrons Bjorn Nilsen The production of heavy quarks in the high energy pre-thermal collision between heavy ions can be used as probes to help understand the nature of the later formed Quark Gluon Plasma and the strong force which dominates there. The semi-leptonic decay of $B$ mesons and $\Sigma$ baryons have a large enough life-time to allow for improved identification. This in turn allows for the study of the effects of the QGP on the properties of the $b$-quark's. An analysis is being developed, based on simulations, to determine the feasibility of such a measurement. Results from this analysis will be presented. [Preview Abstract] |

Q1.00004: Atom Wavelike Nature Solved Mathematically Charles Sven Like N/S poles of a magnet the strong force field surrounding, confining the nucleus exerts an equal force [noted by this author] driving electrons away from the attraction of positively charged protons force fields in nucleus -- the mechanics for wavelike nature of electron. Powerful forces corral closely packed protons within atomic nucleus with a force that is at least a million times stronger than proton's electrical attraction that binds electrons. This then accounts for the ease of electron manipulation in that electron is already pushed away by the very strong atomic N/S force field; allowing electrons to drive photons when I strike a match. Ageless atom's electron requirements, used to drive light/photons or atom bomb, without batteries, must be supplied from a huge, external, super high frequency, super-cooled source, undetected by current technology, one that could exist 14+ billion years without degradation -- filling a limitless space prior to Big Bang. Using only replicable physics, I show how our Universe emanated from that event. [Preview Abstract] |

Q1.00005: Quantum Gravity Shantilal Goradia The continuing search for quantum gravity and never ending attempts to unify gravity with other forces of nature represent tremendous waste of public and private funds directing students' energy towards non-creative manipulative work instead of learning from the scientific creativity in Einstein's 1919 paper that unifies gravity with nuclear force. It reflects Einstein's 1919 jump beyond his own 1915 theory of gravity, including that of Newton as implicitly demanded by Newton in 1686. Einstein corrected and retracted his 1917 introduction of cosmological constant in 1919. Dislike of the fact that Einstein did not use quantum mechanics to prove his point has no real value now, because we will use key ingredients (Planck scale and probabilistic aspect) of quantum mechanics and show that they reach the same conclusion. Newton explained the solar system known after Kepler. Likewise, our quantum mechanical approach explains the strong coupling as well the solar system and shows new horizons, otherwise unexplained. Explanation of unexplained observations need no prediction per Hawking, and obviously otherwise. [Preview Abstract] |

Q1.00006: A Physical Model of the Metric Expansion of Space John Laubenstein At the heart of IWPD's Scale Metrics (ISM) theory is the realization that any orthogonal relationship may be equivalently expressed as a linear relationship multiplied by a mathematical scalar. This has significance in the relationship of a worldline to its 4-Velocity and observed 3-Velocity, as well as in understanding the divergence between energy and momentum as invariant mass increases. Spacetime may be depicted by taking the time dimension within four-dimensional spacetime and rotating it until it becomes embedded as a line segment (or ring) within the three spatial dimensions. This allows velocity and momentum to be determined based upon a linear subtraction of physical entities multiplied by a mathematical scalar (X). We will provide evidence supporting the mathematical and physical significance of this scaling factor along with the benefits of ISM theory. This model provides a physical explanation of the metric expansion of space and addresses many of the current challenges in physics. The model makes predictions that are currently testable with technologies already in place. [Preview Abstract] |

Q1.00007: The Origin of Galactic Rotation Stewart Brekke The early universe consisted of many systems of already formed pre-galactic arms, the arms in orbit about each other. As the orbits of the arms decayed due to gravitational attraction, the fore sections of the arms tangentially collided and stuck together forming spiral galaxies. The orbital motion of the pregalactic arms became transformed into rotational motion of the newly formed spiral galaxies. As the rotational motion of the newly formed spiral galaxies slowed down, the spiral arms collapsed into the body of the galaxy forming elliptical galaxies rotating slower than spiral galaxies.

Q1.00008: The possibility of a Very High Momentum Particle Identification upgrade for Alice Edmundo Garcia The results of RHIC have strongly altered the perception of the baryon production in heavy-ion collisions. From a proton over pion ratio of 9{\%} in the thermal region, above transverse momenta of 3 GeV/c this ratio equals or even surpasses unity. Several theoretical predictions for LHC assume an enhanced baryon production at higher transverse momenta: 10-20 GeV/c. In that optics we have decided to propose to the ALICE collaboration an upgrade of the particle identification capabilities with a new detector of small size 12 square meters. In the first stage we consider building a prototype to be commissioned at the end of 2011. The prototype would consist of a C4F10 gas Cherenkov detector with spherical mirror focusing, and CsI photocathode coupled with MWPCs. The detector would identify pions and kaons up to a momentum of 26 GeV/c with a 4 sigma separation. We will discuss also the possible use of GEMs as a photo detector where encouraging results have been obtained by our protocollaboration. The physics capabilities of such a detector in conjunction with the ALICE experiment will be contemplated. [Preview Abstract] |
