A Coboundary Morphism For The Grothendieck Spectral Sequence
David Baraglia
Given an abelian category with enough injectives we show that a short exact sequence of chain complexes of objects in gives rise to a short exact sequen…
alpha_s from tau decays revisited
D. Boito, O. Cata, M. Golterman +4
Being a determination at low energies, the analysis of hadronic tau decay data provides a rather precise determination of the strong coupling alpha_s after evolving the result to M…
Sub-diffraction thin-film sensing with planar terahertz metamaterials
Withawat Withayachumnankul, Hungyen Lin, Kazunori Serita +6
Planar metamaterials have been recently proposed for thin dielectric film sensing in the terahertz frequency range. Although the thickness of the dielectric film can be very small…
Issues in determining alpha_s from hadronic tau decay and electroproduction data
D. Boito, O. Cata, M. Golterman +4
We discuss some key issues associated with duality-violating and non-perturbative OPE contributions to the theoretical representations of light quark current-current two-point func…
Multi-year search for dark matter annihilations in the Sun with the AMANDA-II and IceCube detectors
IceCube Collaboration, R. Abbasi, Y. Abdou +258
A search for an excess of muon-neutrinos from dark matter annihilations in the Sun has been performed with the AMANDA-II neutrino telescope using data collected in 812 days of live…
Quantum Strategies Win in a Defector-Dominated Population
Qiang Li, Azhar Iqbal, Minyou Chen +1
Quantum strategies are introduced into evolutionary games. The agents using quantum strategies are regarded as invaders whose fraction generally is 1% of a population in contrast t…
Upper limits on a stochastic gravitational-wave background using LIGO and Virgo interferometers at 600-1000 Hz
J. Abadie, B. P. Abbott, R. Abbott +782
A stochastic background of gravitational waves is expected to arise from a superposition of many incoherent sources of gravitational waves, of either cosmological or astrophysical…
Strangeness Contribution to the Proton Spin from Lattice QCD
Gunnar S. Bali, Sara Collins, Meinulf Gockeler +8
We compute the strangeness and light-quark contributions Delta s, Delta u and Delta d to the proton spin in nf=2 lattice QCD at a pion mass of about 285 MeV and at a lattice spacin…
SU(3) centre vortices underpin confinement and dynamical chiral symmetry breaking
Elyse-Ann O'Malley, Waseem Kamleh, Derek Leinweber +1
The mass function of the nonperturbative quark propagator in SU(3) gauge theory shows only a weak dependence on the vortex content of the gauge configurations. Of particular note i…
The Faddeev-Mickelsson-Shatashvili anomaly and lifting bundle gerbes
Pedram Hekmati, Michael K. Murray, Danny Stevenson +1
In gauge theory, the Faddeev-Mickelsson-Shatashvili anomaly arises as a prolongation problem for the action of the gauge group on a bundle of projective Fock spaces. In this paper,…
A lattice study of the strangeness content of the nucleon
G. S. Bali, S. Collins, M. Gockeler +9
We determine the quark contributions to the nucleon spin Delta s, Delta u and Delta d as well as their contributions to the nucleon mass, the sigma-terms. This is done by computing…
Trigger and Aperture of the Surface Detector Array of the Pierre Auger Observatory
J. Abraham, P. Abreu, M. Aglietta +469
The surface detector array of the Pierre Auger Observatory consists of 1600 water-Cherenkov detectors, for the study of extensive air showers (EAS) generated by ultra-high-energy c…
Gravitino cosmology with a very light neutralino
Herbi K. Dreiner, Marja Hanussek, Jong-Soo Kim +1
It has been shown that very light or even massless neutralinos are consistent with all current experiments, given non-universal gaugino masses. Furthermore, a very light neutralino…
A new determination of α_s from hadronic τ decays
Diogo Boito, Oscar Cata, Maarten Golterman +4
We present a new framework for the extraction of the strong coupling from hadronic τdecays through finite-energy sum rules. Our focus is on the small, but still significant non-per…
Simultaneous multi-wavelength campaign on PKS 2005-489 in a high state
The H. E. S. S. Collaboration, the Fermi LAT Collaboration, : +345
The high-frequency peaked BL Lac object PKS 2005-489 was the target of a multi-wavelength campaign with simultaneous observations in the TeV gamma-ray (H.E.S.S.), GeV gamma-ray (Fe…
Search for signatures of magnetically-induced alignment in the arrival directions measured by the Pierre Auger Observatory
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +496
We present the results of an analysis of data recorded at the Pierre Auger Observatory in which we search for groups of directionally-aligned events (or `multiplets') which exhibit…
Discovery of extended VHE γ-ray emission from the vicinity of the young massive stellar cluster Westerlund 1
HESS Collaboration, A. Abramowski, F. Acero +198
Results obtained in very-high-energy (VHE; E > 100 GeV) γ-ray observations performed with the H.E.S.S. telescope array are used to investigate particle acceleration processes in th…
Self similarity and attraction in stochastic nonlinear reaction-diffusion systems
Wei Wang, A. J. Roberts
Similarity solutions play an important role in many fields of science: we consider here similarity in stochastic dynamics. Important issues are not only the existence of stochastic…
Search for Gravitational Waves from Low Mass Compact Binary Coalescence in LIGO's Sixth Science Run and Virgo's Science Runs 2 and 3
the LIGO Scientific Collaboration, the Virgo Collaboration, J. Abadie +796
We report on a search for gravitational waves from coalescing compact binaries using LIGO and Virgo observations between July 7, 2009 and October 20, 2010. We searched for signals…
Oka properties of some hypersurface complements
Alexander Hanysz
Oka manifolds can be viewed as the "opposite" of Kobayashi hyperbolic manifolds. Kobayashi asked whether the complement in projective space of a generic hypersurface of sufficientl…
