CKM Parameters and Rare B Decays (open access)

CKM Parameters and Rare B Decays

Measurements of the angles and sides of the unitarity triangle and of the rates of rare B meson decays are crucial for the precise determination of Standard Model parameters and are sensitive to the presence of new physics particles in the loop diagrams. In this paper the recent measurements performed in this area by BABAR and Belle will be presented. The direct measurement of the angle {alpha} is for the first time as precise as the indirect determination. The precision of the |V{sub ub}| determination has improved significantly with respect to previous measurement. New limits on B {yields} {tau}{nu} decays are presented, as well as updated measurements on b {yields} s radiative transitions and a new observation of b {yields} d{gamma} transition made by Belle.

A Coherent Compton Backscattering High Gain FEL using an X-Band Microwave Undulator (open access)

A Coherent Compton Backscattering High Gain FEL using an X-Band Microwave Undulator

High power microwave sources at X-Band, delivering 400 to 500 of megawatts for about 400 ns, have been recently developed. These sources can power a microwave undulator with short period and large gap, and can be used in short wavelength FELs reaching the nm region at a beam energy of about 1 GeV. We present here an experiment designed to demonstrate that microwave undulators have the field quality needed for high gain FELs.

Coherent States and Spontaneous Symmetry Breaking in Light Front Scalar Field Theory (open access)

Coherent States and Spontaneous Symmetry Breaking in Light Front Scalar Field Theory

Recently developed nuclear many-body techniques provide novel results when applied to constituent quark models and to light-front scalar field theory. We show how spontaneous symmetry breaking arises and is consistent with a coherent state ansatz in a variational treatment. The kink and the kink-antikink topological features are identified and the onset of symmetry restoration is demonstrated.

Detection of Laser Optic Defects Using Gradient Direction Matching (open access)

Detection of Laser Optic Defects Using Gradient Direction Matching

That National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) will be the world's largest and most energetic laser. It has thousands of optics and depends heavily on the quality and performance of these optics. Over the past several years, we have developed the NIF Optics Inspection Analysis System that automatically finds defects in a specific optic by analyzing images taken of that optic. This paper describes a new and complementary approach for the automatic detection of defects based on detecting the diffraction ring patterns in downstream optic images caused by defects in upstream optics. Our approach applies a robust pattern matching algorithm for images called Gradient Direction Matching (GDM). GDM compares the gradient directions (the direction of flow from dark to light) of pixels in a test image to those of a specified model and identifies regions in the test image whose gradient directions are most in line with those of the specified model. For finding rings, we use luminance disk models whose pixels have gradient directions all pointing toward the center of the disk. After GDM identifies potential rings locations, we rank these rings by how well they fit the theoretical diffraction ring pattern equation. We perform …

Evaluating the Moisture Conditions in the Fractured Rock at YuccaMountain: The Impact of Natural Convection Processes in HeatedEmplacement Drifts (open access)

Evaluating the Moisture Conditions in the Fractured Rock at YuccaMountain: The Impact of Natural Convection Processes in HeatedEmplacement Drifts

The energy output of the high-level radioactive waste to beemplaced in the proposed geologic repository at Yucca Mountain, Nevada,will strongly affect the thermal-hydrological (TH) conditions in thenear-drift fractured rock. Heating of rock water to above-boilingconditions will induce large water saturation changes and fluxperturbations close to the waste emplacement tunnels (drifts) that willlast several thousand years. Understanding these perturbations isimportant for the performance of the repository, because they couldincrease, for example, the amount of formation water seeping into theopen drifts and contacting waste packages. Recent computational fluiddynamics (CFD) analysis has demonstrated that the drifts will act asimportant conduits for gas flows driven by natural convection. As aresult, vapor generated from boiling of formation water nearelevated-temperature sections of the drifts may effectively betransported to cooler end sections (where no waste is emplaced), wouldcondense there, and subsequently drain into underlying rock units. Thus,natural convection processes have great potential for reducing thenear-drift moisture content in heated drift sections, which has positiveramifications for repository performance. To study these processes, wehave developed a new simulation method that couples existing tools forsimulating TH conditions in the fractured formation with modules thatapproximate natural convection and evaporation conditions in heatedemplacement drifts. The new method is applied to evaluate the …

Excited Utterances, "Testimonial" Statements, and the Confrontation Clause (open access)

Excited Utterances, "Testimonial" Statements, and the Confrontation Clause

The United States Supreme Court will hear oral argument this term in appeals from two state supreme court cases, Hammon v. Indiana and Davis v. Washington, concerning the admissibility of “excited utterance” statements made by non-testifying witnesses at criminal trials. In the landmark Crawford v. Washington case in 2004, the Court held that the Sixth Amendment’s Confrontation Clause forbids hearsay “testimonial” evidence from being introduced against the accused unless the witness is unavailable to testify and the defendant has had a prior opportunity to crossexamine the witness. However, the Crawford Court declined to provide a comprehensive definition of “testimonial,” leaving such task “for another day.”

Federal Programs with a Financial Eligibility Component (open access)

Federal Programs with a Financial Eligibility Component

Correspondence issued by the Government Accountability Office with an abstract that begins "Each year, federal benefit programs make billions of dollars of improper payments, in some cases, due to inaccurate personal and financial information provided by applicants. For federal agencies administering those programs, getting reliable personal and financial information is vital for making good decisions about whether an individual or business is eligible for federal benefits. As one of the largest repositories of personal and financial information in the United States, IRS has a number of data-sharing relationships with federal agencies to help verify applicant-provided information. This letter conveys information Congress requested as a part of work we conducted on verifying financial information at federal agencies, including the IRS. As agreed, we (1) compiled a listing of federal benefit programs with a financial eligibility component and (2) described documentation requirements to qualify for these programs."

FERMI@Elettra: A Seeded Harmonic Cascade FEL for EUV and Soft X-Rays (open access)

FERMI@Elettra: A Seeded Harmonic Cascade FEL for EUV and Soft X-Rays

We describe the machine layout and major performance parameters for the FERMI FEL project funded for construction at Sincrotrone Trieste, Italy, within the next five years. The project will be the first user facility based on seeded harmonic cascade FEL's, providing controlled, high peak-power pulses. With a high-brightness rf photocathode gun, and using the existing 1.2 GeV S-band linac, the facility will provide tunable output over a range from {approx}100 nm to {approx}10 nm, with pulse duration from 40 fs to {approx} 1ps, peak power {approx}GW, and with fully variable output polarization. Initially, two FEL cascades are planned; a single-stage harmonic generation to operate > 40 nm, and a two-stage cascade operating from {approx}40 nm to {approx}10 nm or shorter wavelength. The output is spatially and temporally coherent, with peak power in the GW range. Lasers provide modulation to the electron beam, as well as driving the photocathode and other systems, and the facility will integrate laser systems with the accelerator infrastructure, including a state-of-the-art optical timing system providing synchronization of rf signals, lasers, and x-ray pulses. Major systems and overall facility layout are described, and key performance parameters summarized.
