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 (open access)

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.

Reflectivity Measurements for Copper and Aluminum in the Far Infrared and the Resistive Wall Impedance in the LCLS Undulator (open access)

Reflectivity Measurements for Copper and Aluminum in the Far Infrared and the Resistive Wall Impedance in the LCLS Undulator

Reflectivity measurements in the far infrared, performed on aluminum and copper samples, are presented and analyzed. Over a frequency range of interest for the LCLS bunch, the data is fit to the free-electron model, and to one including the anomalous skin effect. The models fit well, yielding parameters dc conductivity and relaxation times that are within 30-40% of expected values. We show that the induced energy in the LCLS undulator region is relatively insensitive to variations on this order, and thus we can have confidence that the wake effect will be close to what is expected.

Oral History Interview with John Burks, June 27, 2006 transcript

Oral History Interview with John Burks, June 27, 2006

The National Museum of the Pacific War presents an oral interview with John Burks. Burks was born in Tulsa, Oklahoma on 17 January 1923. After graduating from high school in 1940, he attended the University of Oklahoma until October 1942, at which time he joined the US Army Air Forces. He began a pilot training program, but the Army terminated it. In August 1943, he underwent basic training at Sheppard Field, Texas for twelve weeks. In November, he went to gunnery school at Laredo Air Field in Texas. He was then sent to March Field, California where he was assigned to a B-24 crew as the ball turret gunner. In April 1944 the crew flew to Wheeler Field, Hawaii where they underwent advanced training with the 26th Bomb Squadron, 11th Bomb Group, 7th Air Force. In September 1944 they moved to Kwajalein where they participated in bombing missions over Truk and Wake Islands. During October 1944 they moved to Guam where they flew forty missions over various islands including seventeen missions over Iwo Jima in preparation for the invasion. Burks relates his personal experience of capturing a Japanese soldier while on Guam. He returned to the United States in March …

Conducting Polymer-Inorganic Nanoparticle (CPIN) Nanoarrays for Battery Applications - Final Technical Report (open access)

Conducting Polymer-Inorganic Nanoparticle (CPIN) Nanoarrays for Battery Applications - Final Technical Report

Our objective was to develop new, self-assembling conducting polymer-inorganic nanoparticle nanoarrays (CPIN nanoarrays) comprised of nanoparticles of inorganic Li+ insertion compounds that are “wired” together with oligomeric chains of derivatives of polythiophene. Using these nanoarrays, we developed an understanding of the relationship between structure and electrochemical function for nanostructured materials. Such nanoarrays are expected to have extremely high specific energy and specific power for battery applications due to the unique structural characteristics that derive from the nanoarray. Under this award we developed several synthetic approaches to producing manganese dioxide nanoparticles (NPs). We also developed a layer-by-layer approach for immobilizing these NPs so they could be examined electrochemically. We also developed new synthetic procedures for encapsulating manganese dioxide nanoparticles within spheres of polyethylenedioxythiophene (PEDOT), a conducting polymer with excellent charge-discharge stability. These have a unique manganese dioxide core-PEDOT shell structure. We examined the structures of these systems using transmission electron microscopy, various scanning probe microscopies, and electrochemical measurements. Various technical reports have been submitted that describe the work, including conference presentations, publications and patent applications. These reports are available through http://www.osti.gov, the DOE Energy Link System.

Domain Walls, near-BPS Bubbles and Probabilities in the Landscape (open access)

Domain Walls, near-BPS Bubbles and Probabilities in the Landscape

We develop a theory of static BPS domain walls in stringy landscape and present a large family of BPS walls interpolating between different supersymmetric vacua. Examples include KKLT models, STU models, type IIB multiple flux vacua, and models with several Minkowski and AdS vacua. After the uplifting, some of the vacua become dS, whereas some others remain AdS. The near-BPS walls separating these vacua may be seen as bubble walls in the theory of vacuum decay. As an outcome of our investigation of the BPS walls, we found that the decay rate of dS vacua to a collapsing space with a negative vacuum energy can be quite large. The parts of space that experience a decay to a collapsing space, or to a Minkowski vacuum, never return back to dS space. The channels of irreversible vacuum decay serve as sinks for the probability flow. The existence of such sinks is a distinguishing feature of the landscape. We show that it strongly affects the probability distributions in string cosmology.

An Efficient Vector Finite Element Method for Nonlinear Electromagnetic Modeling (open access)

An Efficient Vector Finite Element Method for Nonlinear Electromagnetic Modeling

We have developed a mixed Vector Finite Element Method (VFEM) for Maxwell's equations with a nonlinear polarization term. The method allows for discretization of complicated geometries with arbitrary order representations of the B and E fields. In this paper we will describe the method and a series of optimizations that significantly reduce the computational cost. Additionally, a series of test simulations will be presented to validate the method. Finally, a nonlinear waveguide mode mixing example is presented and discussed.

U.S.-China Counterterrorism Cooperation: Issues for U.S. Policy

After the terrorist attacks on September 11, 2001, the United States faced a challenge in enlisting the full support of the People's Republic of China (PRC) in counterterrorism. This effort raised short-term policy issues about how to elicit cooperation and how to address China's concerns about military action (Operation Enduring Freedom). Longer-term questions have concerned whether counterterrorism has strategically transformed bilateral relations and whether China's support has been valuable and not obtained at the expense of other U.S. interests.
