Kavli Affiliate: Patricia Burchat | Summary:(Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a single wide-deep-fast sky survey, and LSST will have unique survey capability in the faint time domain. The LSST design is driven […]
Kavli Affiliate: Richard Dubois | Summary:The light curves produced by all-sky monitors, such as the Rossi X-ray Timing Explorer All-Sky Monitor and the Swift Burst Alert Telescope (BAT), generally have non-uniform error bars. In searching for periodic modulation in this type of data using power spectra it can be important to use appropriate weighting of […]
Kavli Affiliate: Richard Dubois | Summary:The Gamma-ray Large Area Space Telescope (GLAST) is a next generation high energy gamma-ray observatory due for launch in Fall 2007. The primary instrument is the Large Area Telescope (LAT), which will measure gamma-ray flux and spectra from 20 MeV to > 300 GeV and is a successor to the […]
Kavli Affiliate: Homer Neal | Summary:A continuing mystery in particle physics is the large polarization observed in inclusive hyperon production in high energy p-p collisions. In this paper the authors advance the concept that the polarization effects can be accounted for in a simple model based on quarks becoming polarized in the direct q-q scattering […]
Kavli Affiliate: Steffen Luitz | Summary:The BaBar experiment is the particle detector at the PEP-II B-factory facility at the Stanford Linear Accelerator Center. During the summer shutdown 2002 the BaBar Event Building and Level-3 trigger farm were upgraded from 60 Sun Ultra-5 machines and 100MBit/s Ethernet to 50 Dual-CPU 1.4GHz Pentium-III systems with Gigabit Ethernet. […]
Kavli Affiliate: Stuart Marshall | Summary:We present an untriggered search for optical bursts with the ROTSE-I telephoto array. Observations were taken which monitor an effective 256 square degree field continuously over 125 hours to m_ROTSE=15.7. The uniquely large field, moderate limiting magnitude and fast cadence of $sim$10 minutes permits transient searches in a new region […]
Kavli Affiliate: Daniel Akerib | Summary:The past few years have seen dramatic breakthroughs and spectacular and puzzling discoveries in astrophysics and cosmology. In many cases, the new observations can only be explained with the introduction of new fundamental physics. Here we summarize some of these recent advances. We then describe several problem in astrophysics and […]
Kavli Affiliate: Richard Partridge | Summary:This paper summarizes a variety of recent results on heavy quark production and decay. Considerable progress has been made by CDF and D0 in measuring top quark production and decay properties. The top quark mass been measured with an uncertainty that is less than 3%, a relative precision that is […]
Kavli Affiliate: Daniel Akerib | Summary:We are conducting an experiment to search for WIMPs, or weakly-interacting massive particles, in the galactic halo using terrestrial detectors. This generic class of hypothetical particles, whose properties are similar to those predicted by extensions of the standard model of particle physics, could comprise the cold component of non-baryonic dark […]
