  • Taylor, Frank E. (American Physical Society, 2012-07)
    A QCD analysis is reported of ATLAS data on inclusive W[superscript ±] and Z boson production in pp collisions at the LHC, jointly with ep deep-inelastic scattering data from HERA. The ATLAS data exhibit sensitivity to the ...
  • Apyan, Aram; Bauer, Gerry P.; Busza, Wit; Cali, Ivan Amos; Chan, M.; Di Matteo, Leonardo; Dutta, V.; Gomez-Ceballos, Guillelmo; Goncharov, Maxim; Gulhan, Doga Can; Kim, Y.; Klute, Markus; Lai, Yue Shi; Levin, A.; Luckey, P. David, Jr.; Teng, Ma; Nahn, Steven; Paus, Christoph M. E.; Roland, Christof E.; Roland, Gunther M.; Stephans, George S. F.; Stockli, Fabian; Sumorok, Konstanty C.; Velicanu, Dragos Alexandru; Wolf, R.; Wyslouch, Boleslaw; Yang, M.; Yilmaz, Yetkin; Yoon, A. S.; Zanetti, Marco; Zhukova, Victoria; Ralph, Duncan Kelley (Elsevier, 2013-12)
    The inclusive cross section for top-quark pair production measured by the CMS experiment in proton–proton collisions at a center-of-mass energy of 7 TeV is compared to the QCD prediction at next-to-next-to-leading order ...
  • Williams, Michael (American Physical Society, 2013-05)
    The quantum numbers of the X(3872) meson are determined to be J[superscript PC]=1[superscript ++] based on angular correlations in B[superscript +]→X(3872)K[superscript +] decays, where X(3872)→π[superscript +]π[superscript ...
  • Alexandrou, Constantia; Gregory, Eric B.; Korzec, Tomasz; Koutsou, Giannis; Negele, John W.; Sato, Toru; Tsapalis, Antonios (American Physical Society, 2013-06)
    We present a lattice QCD calculation of the Δ(1232) matrix elements of the axial-vector and pseudoscalar currents. The decomposition of these matrix elements into the appropriate Lorentz invariant form factors is carried ...
  • Bechtel, Kate L.; Haka, Abigail S.; Shih, Wei-Chuan; Koo, Tae-Woong; Berger, Andrew J.; Feld, Michael S.; Scepanovic, Obrad R. (SPIE, 2007-11)
    The ability to quantify uncertainty in information extracted from spectroscopic measurements is important in numerous fields. The traditional approach of repetitive measurements may be impractical or impossible in some ...
  • Counts, Ian Thomas Hunt; Ilten, Philip James; Williams, M. (Elsevier, 2014-12)
    Using the latest LHCb measurements of time-dependent CP violation in the B[subscript s][superscript 0] → K[superscript +]K[superscript −] decay, a U-spin relation between the decay amplitudes of B[subscript s][superscript ...
  • Alexandrou, Constantia; Petschlies, M.; Strelchenko, A.; Tsapalis, A.; Negele, John W. (American Physical Society, 2013-08)
    A method suitable for extracting resonance parameters of unstable baryons in lattice QCD is examined. The method is applied to the strong decay of the Δ to a pion-nucleon state, extracting the πNΔ coupling constant and Δ ...
  • Vattre, Aurelien J.; Demkowicz, Michael J. (Elsevier, 2013-06)
    A formalism for describing interface dislocation arrays linking the Frank–Bilby equation and anisotropic elasticity theory under the condition of vanishing far-field stresses is developed. The present approach enables the ...
  • Lopez, Laura A.; Marshall, Herman Lee; Canizares, Claude R.; Schulz, Norbert S.; Kane, Julie F. (IOP Publishing, 2006-05)
    We test the physical model of the relativistic jets in the Galactic X-ray binary SS 433 proposed in our previous paper using additional observations from the Chandra High Energy Transmission Grating Spectrometer. These ...
  • Buckley, Martha W.; Ponte, Rui M.; Heimbach, Patrick; Forget, Gael (American Meteorological Society, 2015-05)
    A recent state estimate covering the period 1992–2010 from the Estimating the Circulation and Climate of the Ocean (ECCO) project is utilized to quantify the roles of air–sea heat fluxes and advective heat transport ...
  • McAndrew, Elizabeth G.; Dugast, Anne-Sophie; Licht, Anna F.; Eusebio, Justin R.; Alter, Galit; Ackerman, Margaret E. (MyJoVE Corporation, 2011-11)
    Antibody-driven phagocytosis is induced via the engagement of Fc receptors on professional phagocytes, and can contribute to both clearance as well as pathology of disease. While the properties of the variable domains of ...
  • Holton, Richard (Routledge, 2009-08)
    Some recent studies have suggested that belief in determinism tends to undermine moral motivation: subjects who are given determinist texts to read become more likely to cheat or engage in vindictive behaviour. One possible ...
  • Chandrasekaran, Karthekeyan; Goyal, Navin; Haeupler, Bernhard (Society for Industrial and Applied Mathematics, 2013-11)
    The Lovász local lemma (LLL) [P. Erdös and L. Lovász, Problems and results on 3-chromatic hypergraphs and some related questions, in Infinite and Finite Sets, Vol. II, A. Hajnal, R. Rado, and V. T. Sós, eds., North--Holland, ...
  • Chudzicki, Christopher Alan; Shapiro, Jeffrey H.; Chuang, Isaac L. (American Physical Society, 2013-04)
    Previous analyses of conditional φ[subscript nl]-phase gates for photonic qubits that treat cross-phase modulation (XPM) in a causal, multimode, quantum field setting suggest that a large (∼π rad) nonlinear phase shift is ...
  • Sheffield, Scott Roger (American Mathematical Society (AMS), 2013-06)
    Within classical optics, one may add microscopic "roughness'' to a macroscopically flat mirror so that parallel rays of a given angle are reflected at different outgoing angles. Taking the limit (as the roughness becomes ...
  • Thompson, J. D.; Tiecke, T. G.; de Leon, N. P.; Feist, J.; Akimov, A. V.; Gullans, Michael; Zibrov, A. S.; Lukin, M. D.; Vuletic, Vladan (American Association for the Advancement of Science (AAAS), 2013-04)
    Hybrid quantum devices, in which dissimilar quantum systems are combined in order to attain qualities not available with either system alone, may enable far-reaching control in quantum measurement, sensing, and information ...
  • Goemans, Michel X.; Iwata, Satoru; Zenklusen, Rico (Institute of Electrical and Electronics Engineers (IEEE), 2010-01)
    Motivated by the deterministic wireless information flow model introduced by Avestimehr, Diggavi and Tse, we introduce a deterministic flow model based on combining polylinking systems, a notion introduced by Schrijver and ...
  • Leiserson, Charles E.; Sukha, Jim; Schardl, Tao Benjamin (Association for Computing Machinery (ACM), 2012-02)
    Existing concurrency platforms for dynamic multithreading do not provide repeatable parallel random-number generators. This paper proposes that a mechanism called pedigrees be built into the runtime system to enable efficient ...
  • Eddy, Matthew T.; Ruben, David; Herzfeld, Judith; Griffin, Robert Guy (Elsevier, 2011-12)
    We show that a simple, general, and easily reproducible method for generating non-uniform sampling (NUS) schedules preserves the benefits of random sampling, including inherently reduced sampling artifacts, while removing ...

    This paper presents an algorithm for finding approximately optimal policies in very large Markov decision processes by constructing a hierarchical model and then solving it approximately. It exploits factored representations ...
