Beam-Spin Asymmetries in the Azimuthal Distribution of Pion Electroproduction
HERMES Collaboration, A. Airapetian
A measurement of the beam-spin asymmetry in the azimuthal distribution of pions produced in semi-inclusive deep-inelastic scattering off protons is presented. The measurement was p…
Isomorphisms of algebras of Colombeau generalized functions
Hans Vernaeve
We show that for smooth manifolds X and Y, any isomorphism between the special algebra of Colombeau generalized functions on X, resp. Y is given by composition with a unique Colomb…
Radial stability of a family of anisotropic Hernquist models with and without a supermassive black hole
P. Buyle, E. Van Hese, S. De Rijcke +1
We present a method to investigate the radial stability of a spherical anisotropic system that hosts a central supermassive black hole (SBH). Such systems have never been tested be…
UV finiteness of 3D Yang-Mills theories with a regulating mass in the Landau gauge
D. Dudal, J. A. Gracey, R. F. Sobreiro +2
We prove that three-dimensional Yang-Mills theories in the Landau gauge supplemented with a infrared regulating, parity preserving mass term are ultraviolet finite to all orders. W…
Regge-plus-resonance treatment of the p(gamma,K^+)Sigma^0 and p(gamma,K^0)Sigma^+ reactions at forward kaon angles
T. Corthals, D. G. Ireland, T. Van Cauteren +1
An effective-Lagrangian framework for K Sigma photoproduction from the proton is presented. The proposed model is applicable at forward kaon angles and photon lab energies from thr…
Beam-helicity asymmetry in photon and pion electroproduction in the Delta(1232) resonance region at Q^2= 0.35 (GeV/c)^2
A1 Collaboration, I. K. Bensafa, P. Achenbach +40
The beam-helicity asymmetry has been measured simultaneously for the reactions (e p \to e p γ) and (e p \to e p π^0) in the resonance region at 0.35 (GeV/c). T…
A classification of generalized quantum statistics associated with the exceptional Lie (super)algebras
N. I. Stoilova, J. Van der Jeugt
Generalized quantum statistics (GQS) associated to a Lie algebra or Lie superalgebra extends the notion of para-Bose or para-Fermi statistics. Such GQS have been classified for all…
Completely analytical families of anisotropic gamma-models
Pieter Buyle, Chris Hunter, Herwig Dejonghe
We present new analytical distribution functions for anisotropic spherical galaxies. They have the density profiles of the gamma-models, which allow a wide range of central density…
Dimension two gluon condensates in a variety of gauges and a gauge invariant Yang-Mills action with a mass
D. Dudal, M. A. L. Capri, J. A. Gracey +4
We give a short overview of our work concerning the dimension two operator A^2 in the Landau gauge and its generalizations to other gauges. We conclude by discussing recent work th…
Five years of searches for point sources of astrophysical neutrinos with the AMANDA-II neutrino telescope
A. Achterberg
We report the results of a five-year survey of the northern sky to search for point sources of high energy neutrinos. The search was performed on the data collected with the AMANDA…
Purely radiative irrotational dust spacetimes
N Van den Bergh, B Bastiaensen, H R Karimian +1
We consider irrotational dust spacetimes in the full non-linear regime which are "purely radiative" in the sense that the gravitational field satisfies the covariant transverse con…
Precise determination of the spin structure function of the proton, deuteron and neutron
The HERMES Collaboration, A. Airapetian
Precise measurements of the spin structure functions of the proton and deuteron are presented over the kinematic range and $0…
Pathways: Augmenting interoperability across scholarly repositories
Simeon Warner, Jeroen Bekaert, Carl Lagoze +3
In the emerging eScience environment, repositories of papers, datasets, software, etc., should be the foundation of a global and natively-digital scholarly communications system. T…
Existence of Density Functionals for Excited States and Resonances
B. G. Giraud, K. Kato, A. Ohnishi +1
We show how every bound state of a finite system of identical fermions, whether a ground state or an excited one, defines a density functional. Degeneracies created by a symmetry g…
The Binary Nucleus in VCC 128: A Candidate Supermassive Black Hole in a Dwarf Elliptical Galaxy
Victor P. Debattista, Ignacio Ferreras, Anna Pasquali +3
{\it Hubble Space Telescope} (\hst) Wide Field Planetary Camera 2 ({\it WFPC2}) images of the Virgo Cluster dwarf elliptical galaxy VCC 128 reveal an apparently double nucleus. The…
Gribov ambiguities in the maximal Abelian gauge
D. Dudal, M. A. L. Capri, J. A. Gracey +5
The effects of the Gribov copies on the gluon and ghost propagators are investigated in SU(2) Euclidean Yang-Mills theory quantized in the maximal Abelian gauge. By following Gribo…
The CO content of the Local Group dwarf irregular galaxies IC5152, UGCA438, and the Phoenix dwarf
Pieter Buyle, Dolf Michielsen, Sven De Rijcke +2
We present a search for CO(1->0) emission in three Local Group dwarf irregular galaxies: IC5152, the Phoenix dwarf, and UGCA438, using the ATNF Mopra radio telescope. Our scans lar…
The v_c-sigma_c relation in low mass and low surface brightness galaxies
Pieter Buyle, Laura Ferrarese, Gianfranco Gentile +3
We present an updated investigation of the relation between large scale disk circular velocity, v_c, and bulge velocity dispersion, sigma_c. New bulge velocity dispersions are meas…
Quasiparticle properties in a density functional framework
D. Van Neck, S. Verdonck, G. Bonny +2
We propose a framework to construct the ground-state energy and density matrix of an N-electron system by solving selfconsistently a set of single-particle equations. The method ca…
