[S8.002] The Quest for the Higgs Boson and the Planck Black Hole Production at the CERN Large Hadron Collider

Nassim Haramein, E.A. Rauscher (The Resonance Project)

When the CERN 7 TeV Large Hadron Collider (LHC) comes on line in the next few years, hypothesis is that significant experimental discoveries may verify the Higgs boson and the production of short lived Planck size mini Schwarzchild black holes, both of which are fundamental to a unified particle and cosmological standard and supersymmetry model. The Higgs mechanism relates to particle mass in the standard model and the mini black holes may relate to the cosmological mini mass problem as well as yield clues as to the structure of the vacuum. These points are of particular interest to our research [1,2], and the discovery and identification of mini black holes (mbh) is basic to our scaling law model [1]. Hawking radiation from the production of mini black holes from accelerated Hadrons are expected to be observed from x – and \gamma – ray lepton production from subcomponents of quarks or partons. Our model [1,2] and Hawking’s picture [3] may demonstrate that mbh hold basic clues about the very nature of the fabric of spacetime itself. We examine the Kerr-Newman black hole production cross section in detail at the energies of the LHC.

[S8.003] Puzzles and Prospects in String Thermodynamics

Michael Lennek (University of Arizona)

One of the most intriguing features of string thermodynamics is the phenomenon of thermal duality, which relates the physics at temperature T to the physics at inverse temperature 1/T. Unfortunately, the classical definitions of thermodynamic quantities such as entropy and specific heat are not invariant under thermal duality transformations. In this talk, I will discuss several novel approaches towards dealing with this issue. One of these involves extending the usual definition of entropy by introducing additional terms that are suppressed by powers of the string scale. At high temperatures, however, these terms become significant and lead to a variety of surprising new phenomena. This talk reports on work done in collaboration with my Ph.D. advisor, Keith Dienes.

[S8.004] A QCD Generated Mass Spectrum

Burra Gautam Sidharth (Centre for App. Math.amp; Comp. Sc., B.M.Birla Science Centre, Hyderabad 500063)

We deduce a mass formula for all known elementary particles, using the interquark interaction.The error in about 63 percent of the cases is less than one percent while in 93 percent of the cases is less than two percent and in all cases less than three percent with a single exceptional case where the error is 3.6 percent. The recently discovered Ds(2317) meson and the 1.5 Gev pentaquark are also included.

[S8.005] Effective Field Theory Approach to Nucleon Compton Scattering

William Hockings (University of Arizona)

I derive the cross section for Compton scattering on the nucleon at energies below the pion mass. In the first step I write down the most general Lagrangian for nucleon-photon interactions which obeys Lorentz invariance, gauge invariance, parity, time reversal, hermiticity, and reparameterization invariance. This Lagrangian gives Feynman rules which are used to obtain the Compton scattering amplitude as an expansion in powers of ømega/M, where ømega is the photon momentum and M is one of the two mass scales in the theory, either the nucleon mass m_N or the pion mass m_\pi. I compare the cross section in the first two orders to experimental data, and obtain values for the electric and magnetic polarizabilities of the proton.

[S8.006] Patching Up the Lithium Problem - Neutrino Degeneracy to the Rescue?

Thomas Topel (Colorado State University), George Fuller (University of California, San Diego)

Recent measurements of the primordial deuterium abundance in high-redshift clouds toward several several QSOs allow the baryon-to-photon ratio to be accurately pegged. With the baryon-to-photon ratio in hand, standard BBN theory can now make tight predictions for the light element abundances coming out of big bang nucleosynthesis. At the deuterium-set baryon-to-photon ratio, the predicted primeval Li-7 abundance is arguably a factor of three to four larger than that observed in metal-poor halo stars. At present, it is unclear if lithium depletion in these old Population II stars can account for the wide disparity. In this work, we consider how the gap between predicted and observed Li-7 abundances may be narrowed by allowing for neutrino degeneracy. Using the BBN code of Kawano, we find that a positive and equal degeneracy in each of the neutrino species can lower the predicted Li-7/H yield, thus patching up the lithium problem.

[S8.007] Neutrino Mass Search with Single Ba+ Ion Detection

Kendy Hall, Shie-Chang Jeng, Wade Taylor, William M Fairbank (Department of Physics, Colorado State University), Mitsuhiro Miyajima (Department of Applied Physics, Fukui University, Japan)

A new method to search for the neutrino mass is being developed: zero neutrino double beta decay efficient 136Ba+ daughter ion tagging by laser induced fluorescence in a liquid Xe time-projection chamber. We report new measurements of the fluorescence spectrum of Ba+ in liquid Xe using a spectrometer with liquid nitrogen cooled CCD camera. We also use the CCD camera to capture a real time fluorescence image of the Ba+ ion cloud and determine the survival time of the Ba+ ions. New results are presented for the mobility of Ba+, Tl+, Mg+, Ca+, and Sr+ in liquid Xe.

[S8.008] Finding signatures of direct cherenkov radiation in Utah7 telescope array data samples

Daniel Allen, David Kieda (University of Utah), University of Utah Gammaray Team

We discuss the possibility of detecting cherenkov radiation emitted by the primary particle in an extensive air shower. By measuring the characteristics of this radiation, the energy and charge of the primary particle can be determined. Data gathered by the japaneses Utah7 telescope array were analyzed in order to determine if such events have been recorded. Results of this study and possibilities for future study are discussed.

[S8.009] Systematic Errors in Particle Lifetime Measurements

Steve Wasserbaech, Eric Brown (Utah Valley State College)

We studied the systematic uncertainties in measurements of the mean lifetime of the \tau lepton. Different analysis methods are compared, and briefly described. The effects resulting from uncertainties in the positioning of sensitive elements in the detector are explored. These effects are investigated with the use of a simulation of e^+e^- collisions in the ALEPH detector at CERN. Preliminary results of this investigation are reviewed.
