Gondolo, Paolo | Effects of the Sagittarius dwarf tidal stream on dark matter detectors | The Sagittarius dwarf tidal stream may be showering dark matter onto the solar neighborhood, which can change the results and interpretation of direct detection searches for weakly interacting massive particles (WIMPs). Stars in the stream may already have been detected in the solar neighborhood, an... | Sagittarius dwarf galaxy; Sgr stream; WIMP; Weakly interacting massive particles | 2004-03 |

DeTar, Carleton | Excited states in staggered meson propagators | We report on preliminary results from multi-particle fits to meson propagators with three flavors of light dynamical quarks. We are able to measure excited states in propagators with pion quantum numbers, which we interpret as the pion 2S state, and argue is evidence of locality of the action. In t... | Excited states; Meson propagators | 2004-03 |

Mishchenko, Eugene | Fluctuations of radiation from a chaotic laser below threshold | Radiation from a chaotic cavity filled with gain medium is considered. A set of coupled equations describing the photon density and the population of gain medium is proposed and solved. The spectral distribution and fluctuations of the radiation are found. The full noise is a result of a competitio... | Chaotic laser | 2004-03 |

Liu, Feng | Geometric constant defining shape transitions of carbon nanotubes under pressure | We demonstrate that when a single-walled carbon nanotube is under pressure it undergoes a series of shape transitions, first transforming from a circle to an oval and then from an oval to a peanut. Most remarkably, the ratio of the area of the tube cross sections at the second transition over that ... | Geometric constant; Shape transitions; Carbon nanotubes; Pressure | 2004-03 |

Arlitsch, Kenning; Herbert, John | Microfilm, paper, and OCR: issues in newspaper digitization at the Utah digital newspapers program | Describes the issues surrounding digitizing newspapers from microfilm and paper in the Utah Digital Newspapers program. The paper also explores optical character recognition (OCR) accuracy and the problems of digital file storage of newspapers. | Digital libraries; Microfilms, Deterioration; Newspaper office libraries | 2004-03 |

DeTar, Carleton | Phase diagram of high temperature QCD with three flavors of improved staggered quarks | We report on progress in our study of high temperature QCD with three flavors of improved staggered quarks. Simulations are being carried out with three degenerate quarks with masses less than or equal to the strange quark mass, ms, and with degenerate up and down quarks with masses in the range 0... | Staggered quarks | 2004-03 |

DeTar, Carleton | Quark loop effects in semileptonic form factors for heavy-light mesons | We present preliminary results of a determination of the semileptonic form factor for the decay of pseudoscalar heavy-light mesons to pseudoscalar light-light mesons in full QCD. In this preliminary study we focus on the effects of dynamical quark loops. Accordingly, we compare results of simulati... | Semileptonic decay; Form factors; Quark loops; Wilson quarks | 2004-03 |
