Secret Sessions of Congress: A Brief Historical Overview (open access)

Secret Sessions of Congress: A Brief Historical Overview

"Secret" or "closed door" sessions of the House of Representatives and Seante are held periodically to discuss business, including impeachment deliberations, deemed to require confidentiality and secrecy. Authority for the two chambers to hold these sessions is implied by Article I, Section 5, of the Constitution. National Security is the principal reason for such sessions in recent years. This report provides a historical background of such sessions, as well as relevant regulations and expectations for Members of Congress during such sessions.

Simulation of BaBar Drift Chamber (open access)

Simulation of BaBar Drift Chamber

The BaBar drift chamber (DCH) is used to measure the properties of charged particles created from e{sup +}e{sup -} collisions in the PEP-II asymmetric-energy storage rings by making precise measurements of position, momentum and ionization energy loss (dE/dx). In October of 2005, the PEP-II storage rings operated with a luminosity of 10 x 10{sup 33} cm{sup -2}s{sup -1}; the goal for 2007 is a luminosity of 20 x 10{sup 33} cm{sup -2}s{sup -1}, which will increase the readout dead time, causing uncertainty in drift chamber measurements to become more significant in physics results. The research described in this paper aims to reduce position and dE/dx uncertainties by improving our understanding of the BaBar drift chamber performance. A simulation program--called GARFIELD--is used to model the behavior of the drift chamber with adjustable parameters such as gas mixture, wire diameter, voltage, and magnetic field. By exploring the simulation options offered in GARFIELD, we successfully produced a simulation model of the BaBar drift chamber. We compared the time-to-distance calibration from BaBar to that calculated by GARFIELD to validate our model as well as check for discrepancies between the simulated and calibrated time-to-distance functions, and found that for a 0{sup o} entrance angle there …

Deployment and Operation of the ES-3100 Type B Shipping Container (open access)

Deployment and Operation of the ES-3100 Type B Shipping Container

The U.S. Department of Energy (DOE) National Nuclear Security Administration (NNSA) is shipping, for disposition purposes, bulk quantities of fissile materials, primarily highly enriched uranium (HEU). The U.S. Department of Transportation (DOT) specification 6M container has been the workhorse for NNSA and many other shippers of radioactive material since the 1980s. However, the 6M does not conform to the packaging requirements in the Code of Federal Regulations (10 CFR 71) and, for that reason, is being phased out for use in the DOE secure transportation system by the end of 2006. BWXT Y-12 developed and licensed the ES-3100 container to replace the DOT 6M. The ES-3100 was certified by the Nuclear Regulatory Commission (NRC) in April 2006. The process of deploying the new package began in June 2005 and is planned to be completed in July 2006. The package will be fully operational and completely replace the DOT 6M at the Y-12 National Security Complex (Y-12) by October 2006. This paper reviews the deployment process and the mock loading station that was installed at National Transportation Research Center (NTRC) of Oak Ridge National Laboratory. Specialized equipment, tools, and instrumentation that support the handling and loading operations of the ES-3100 are …

Northern Ireland: The Peace Process (open access)

Northern Ireland: The Peace Process

For years, the British and Irish governments have sought to facilitate a peaceful settlement to the conflict in Northern Ireland. After many ups and downs, the two government and the parties participating in the peace talks announced an agreement on April 10, 1998. The implementation of the resulting Good Friday Agreement continues to be difficult. A political stalemate in Northern Ireland since 2002 has halted the peace process and forced London to suspend the devolved government and to resume governance of the province. British and Irish leaders have set a November 24, 2006, deadline to revive talks on governance in Northern Ireland.

A Catalog of Candidate High-redshift Blazars for GLAST (open access)

A Catalog of Candidate High-redshift Blazars for GLAST

High-redshift blazars are promising candidates for detection by the Gamma-ray Large Area Space Telescope (GLAST). GLAST, expected to be launched in the Fall of 2007, is a high-energy gamma-ray observatory designed for making observations of celestial gamma-ray sources in the energy band extending from 10 MeV to more than 200 GeV. It is estimated that GLAST will find several thousand blazars. The motivations for measuring the gamma-ray emission from distant blazars include the study of the high-energy emission processes occurring in these sources and an indirect measurement of the extragalactic background light. In anticipation of the launch of GLAST we have compiled a catalog of candidate high-redshift blazars. The criteria for sources chosen for the catalog were: high radio emission, high redshift, and a flat radio spectrum. A preliminary list of 307 radio sources brighter than 70mJy with a redshift z {ge} 2.5 was acquired using data from the NASA Extragalactic Database. Flux measurements of each source were obtained at two or more radio frequencies from surveys and catalogs to calculate their radio spectral indices {alpha}. The sources with a flat-radio spectrum ({alpha} {le} 0.5) were selected for the catalog, and the final catalog includes about 200 sources.

Observation of e+e- Annihilations into the C=+1 Hadronic Final States \rho^0\rho^0 and \phi\rho^0 (open access)

Observation of e+e- Annihilations into the C=+1 Hadronic Final States \rho^0\rho^0 and \phi\rho^0

The authors report the first observation of e{sup +}e{sup -} annihilations into states of positive C-parity, namely {rho}{sup 0}{rho}{sup 0} and {phi}{rho}{sup 0}. The two states are observed in the {pi}{sup +}{pi}{sup -}{pi}{sup +}{pi}{sup -} and K{sup +}K{sup -} {pi}{sup +}{pi}{sup -} final states, respectively, in a data sample of 225 fb{sup -1} collected by the BABAR experiment at the PEP-II e{sup +}e{sup -} storage rings at energies near {radical}s = 10.58 GeV. The distributions of cos {theta}*, where {theta}* is the center-of-mass polar angle of the {phi} meson or the forward {rho}{sup 0} meson, suggest production by two-virtual-photon annihilation. They measure cross sections within the range |cos {theta}*| < 0.8 of {sigma}(e{sup +}e{sup -} {yields} {rho}{sup 0} {rho}{sup 0}) = 20.7 {+-} 0.7(stat) {+-} 2.7(syst) fb and {sigma}(e{sup +}e{sup -} {yields} {phi}{rho}{sup 0}) = 5.7 {+-} 0.5(stat) {+-} 0.8(syst) fb.

Search for the decay B^0 --> K^0_S K^0_S K^0_L (open access)

Search for the decay B^0 --> K^0_S K^0_S K^0_L

The authors present the first search for the decay B{sup 0} {yields} K{sub S}{sup 0} K{sub S}{sup 0} K{sub L}{sup 0} using a data sample of 232 million B{bar B} pairs. They find no statistically significant evidence for the non-resonant component of this decay. Our central value for the branching fraction, assuming the tru Dalitz distribution is uniform and excluding the {phi} resonance, is {Beta}(B{sup 0} {yields} K{sub S}{sup 0} K{sub S}{sup 0} K{sub L}{sup 0}) = (2.4{sub -2.5}{sup +2.7} {+-} 0.6) x 10{sup -6} where the errors are statistical and systematic, respectively. They set a single-side Bayesian upper limit of {Beta}(B{sup 0} {yields} K{sub S}{sup 0} K{sub S}{sup 0} K{sub L}{sup 0}) < 6.4 x 10{sup -6} at 90% confidence level using a uniform prior probability for physical values. Assuming the worst-case true Dalitz distribution, where the signal is entirely in the region of lowest efficiency, the 90% confidence level upper limit is {Beta}(B{sup 0} {yields} K{sub S}{sup 0} K{sub S}{sup 0} K{sub L}{sup 0}) < 14 x 10{sup -6}.

Search for the decay of a B0 or B0bar meson to K*0bar K0 or K*0 K0bar

The authors present a search for the decay of a B{sup 0} or {bar B}{sup 0} meson to a {bar K}*{sup 0} K{sup 0} or K*{sup 0} {bar K}{sup 0} final state, using a sample of approximately 232 million B{bar B} events collected with the BABAR detector at the PEP-II asymmetric energy e{sup +}e{sup -} collider at SLAC. The measured branching fraction is {Beta}(B{sup 0} {yields} {bar K}*{sup 0} K{sup 0}) + {Beta}(B{sup 0} {yields} K*{sup 0} {bar K}{sup 0}) = (0.2{sub -0.8, -0.3}{sup +0.9, +0.1}) x 10{sup -6}. They obtain the following upper limit for the branching fraction at 90% confidence level: {Beta}(B{sup 0} {yields} {bar K}*{sup 0} K{sup 0}) + {Beta}(B{sup 0} {yields} K*{sup 0} {bar K}{sup 0}) < 1.9 x 10{sup -6}. They use our result to constrain the Standard Model prediction for the deviation of the CP asymmetry in B{sup 0} {yields} {phi}K{sup 0} from sin 2{beta}.

The Two-loop Anomalous Dimension Matrix for Soft Gluon Exchange (open access)

The Two-loop Anomalous Dimension Matrix for Soft Gluon Exchange

The resummation of soft gluon exchange for QCD hard scattering requires a matrix of anomalous dimensions. We compute this matrix directly for arbitrary 2 {yields} n massless processes for the first time at two loops. Using color generator notation, we show that it is proportional to the one-loop matrix. This result reproduces all pole terms in dimensional regularization of the explicit calculations of massless 2 {yields} 2 amplitudes in the literature, and it predicts all poles at next-to-leading order in any 2 {yields} n process that has been computed at next-to-leading order. The proportionality of the one- and two-loop matrices makes possible the resummation in closed form of the next-to-next-to-leading logarithms and poles in dimensional regularization for the 2 {yields} n processes.

Using Boosted Decision Trees to Separate Signal and Background in B to XsGamma Decays (open access)

Using Boosted Decision Trees to Separate Signal and Background in B to XsGamma Decays

The measurement of the branching fraction of the flavor changing neutral current B {yields} X{sub s}{gamma} transition can be used to expose physics outside the Standard Model. In order to make a precise measurement of this inclusive branching fraction, it is necessary to be able to effectively separate signal and background in the data. In order to achieve better separation, an algorithm based on Boosted Decision Trees (BDTs) is implemented. Using Monte Carlo simulated events, ''forests'' of trees were trained and tested with different sets of parameters. This parameter space was studied with the goal of maximizing the figure of merit, Q, the measure of separation quality used in this analysis. It is found that the use of 1000 trees, with 100 values tested for each variable at each node, and 50 events required for a node to continue separating give the highest figure of merit, Q = 18.37.

Partitioned Waveform Inversion Applied to Eurasia and Northern Africa (open access)

Partitioned Waveform Inversion Applied to Eurasia and Northern Africa

This report summarizes the data analysis achieved during Heather Bedle's eleven-week Technical Scholar internship at Lawrence Livermore National Labs during the early summer 2006. The work completed during this internship resulted in constraints on the crustal and upper mantle S-velocity structure in Northern Africa, the Mediterranean, the Middle East, and Europe, through the fitting of regional waveform data. This data extends current raypath coverage and will be included in a joint inversion along with data from surface wave group velocity measurements, S and P teleseismic arrival time data, and receiver function data to create an improved velocity model of the upper mantle in this region. The tectonic structure of the North African/Mediterranean/Europe/Middle Eastern study region is extremely heterogeneous. This region consists of, among others, stable cratons and platforms such as the West Africa Craton, and Baltica in Northern Europe; oceanic subduction zones throughout the Mediterranean Sea where the African and Eurasian plate collide; regions of continental collision as the Arabian Plate moves northward into the Turkish Plate; and rifting in the Red Sea, separating the Arabian and Nubian shields. With such diverse tectonic structures, many of the waveforms were difficult to fit. This is not unexpected as the waveforms are …
