Light quark electromagnetic structure of baryons
J. N. Hedditch, B. G. Lasscock, D. B. Leinweber +3
Fascinating aspects of the light quark-mass behavior of baryon electromagnetic form factors are highlighted. Using FLIC fermions on quenched -improv…
XMM-Newton observations of HESS J1813-178 reveal a composite Supernova remnant
S. Funk, J. A. Hinton, Y. Moriguchi +10
We present X-ray and 12CO(J=1-0) observations of the very-high-energy (VHE) gamma-ray source HESS J1813-178 with the aim of understanding the origin of the gamma-ray emission. Usin…
The Joint Extraction of m_s and V_us From Hadronic Tau Decay Data
K. Maltman, C. E. Wolfe
We discuss the simultaneous determination of m_s and V_us from flavor-breaking hadronic tau decay sum rules, focussing on weight choices designed to better control problems associa…
OPE Constraints and the Leading Order Hadronic Contribution to (g-2)_mu
Kim Maltman
OPE constraints are studied as a means of distinguishing between the versions of the I=1 vector spectral function extracted from (i) inclusive I=1 hadronic electroproduction cross-…
Extended Double Lattice BRST, Curci-Ferrari Mass and the Neuberger Problem
M. Ghiotti, L. von Smekal, A. G. Williams
We present Extended Double BRST on the lattice and extend the Neuberger problem to include the ghost/anti-ghost symmetric formulation of the non-linear covariant Curci-Ferrari (CF)…
Integrability Criterion for Abelian Extensions of Lie Groups
Pedram Hekmati
We establish a criterion for when an abelian extension of infinite-dimensional Lie algebras integrates to a corresponding Lie group extension of by , where is…
Higher Symmetries of the Square of the Laplacian
Michael Eastwood, Thomas Leistner
The symmetry operators for the Laplacian in flat space were recently described and here we consider the same question for the square of the Laplacian. Again, there is a close conne…
Erratum: Detection of diffuse TeV gamma-ray emission from the nearby starburst galaxy NGC 253
C. Itoh, R. Enomoto, S. Yanagita +1
The CANGAROO-II telescope observed sub-TeV gamma-ray emission from the nearby starburst galaxy NGC 253. The emission region was extended with a radial size of 0.3-0.6 degree. On th…
Phase transition from hadronic matter to quark matter
P. Wang, A. W. Thomas, A. G. Williams
We study the phase transition from nuclear matter to quark matter within the SU(3) quark mean field model and NJL model. The SU(3) quark mean field model is used to give the equati…
Quark-gluon vertex in general kinematics
Ayse Kizilersu, Derek B. Leinweber, Jon-Ivar Skullerud +1
We compute the quark-gluon vertex in quenched lattice QCD, in the Landau gauge using an off-shell mean-field O(a)-improved fermion action. The Dirac-vector part of the vertex is co…
Searching for a Stochastic Background of Gravitational Waves with LIGO
LIGO Scientific Collaboration
The Laser Interferometer Gravitational-wave Observatory (LIGO) has performed the fourth science run, S4, with significantly improved interferometer sensitivities with respect to pr…
Renormalized Effective Actions in Radially Symmetric Backgrounds I: Partial Wave Cutoff Method
Gerald V. Dunne, Jin Hur, Choonkyu Lee
The computation of the one-loop effective action in a radially symmetric background can be reduced to a sum over partial-wave contributions, each of which is the logarithm of an ap…
Noise improvement of SNR gain in parallel array of bistable dynamic systems by array stochastic resonance
Fabing Duan, Francois Chapeau-Blondeau, Derek Abbott
We report the regions where a signal-to-noise ratio (SNR) gain exceeding unity exists in a parallel uncoupled array of identical bistable systems, for both subthreshold and suprath…
On the Search For Transits of the Planets Orbiting Gl 876
P. D. Shankland, E. J. Rivera, G. Laughlin +14
We report the results of a globally coordinated photometric campaign to search for transits by the P ~ 30 d and P ~ 60 d outer planets of the 3-planet system orbiting the nearby M-…
CANGAROO-III Observations of the supernova remnant RX J0852.04622
R. Enomoto, S. Watanabe, T. Tanimori et al
Sub-TeV gamma-ray emission from the North-West rim of the supernova remnant RX J0852.04622 was detected with the CANGAROO-II telescope and recently confirmed by the H.E.S.S. gro…
Dessins d'enfants and differential equations
Finnur Larusson, Timur Sadykov
We state and solve a discrete version of the classical Riemann-Hilbert problem. In particular, we associate a Riemann-Hilbert problem to every dessin d'enfants. We show how to comp…
Scaling graphs of heart rate time series in athletes demonstrate the VLF, LF and HF regions
M Baumert, LM Brechtel, J Lock +2
Scaling analysis of heart rate time series has emerged as an useful tool for assessment of autonomic cardiac control. We investigate the heart rate time series of ten athletes (fiv…
Formal Adjoints and a Canonical Form for Linear Operators
Michael G. Eastwood, A. Rod Gover
We describe a canonical form for linear differential operators that are formally self-adjoint or formally skew-adjoint.
V_us From Hadronic Tau Decays
K. Maltman, C. E. Wolfe
We study extractions of |V_us| based on finite energy sum rule (FESR) analyses of hadronic tau decay data. We show (i) that the ``(0,0) spectral weight'' implementation (proposed p…
Can D-Branes Wrap Nonrepresentable Cycles?
Jarah Evslin, Hisham Sati
Sometimes a homology cycle of a nonsingular compactification manifold cannot be represented by a nonsingular submanifold. We want to know whether such nonrepresentable cycles can b…
D-Branes, RR-Fields and Duality on Noncommutative Manifolds
Jacek Brodzki, Varghese Mathai, Jonathan Rosenberg +1
We develop some of the ingredients needed for string theory on noncommutative spacetimes, proposing an axiomatic formulation of T-duality as well as establishing a very general for…
Anisotropy studies around the galactic centre at EeV energies with the Auger Observatory
The Pierre Auger Collaboration
Data from the Pierre Auger Observatory are analyzed to search for anisotropies near the direction of the Galactic Centre at EeV energies. The exposure of the surface array in this…
