Diffractive Vector Meson Production with a Large Momentum Transfer
Rikard Enberg, Jeff Forshaw, Leszek Motyka +1
We summarise recent progress in the computation of helicity amplitudes for diffractive vector meson production at large momentum transfer and their comparison to data collected at…
The ppbar -> tbH^+/- Process at the Tevatron in HERWIG and PYTHIA Simulations
Johan Alwall, Catherine Biscarat, Stefano Moretti +2
Charged Higgs boson production in association with a top quark could be the first indication of the existence of Higgs particles. The Tevatron Run-II started data-taking in April 2…
Anomalous Ferromagnetism of Monatomic Co Wire at the Pt(111) Surface Step Edge
Alexander B. Shick, Frantishek Maca, Peter M. Oppeneer
A first-principles investigation of the anomalous ferromagnetism of a quasi-one-dimensional Co chain at the Pt(111) step edge is reported. Our calculations show that the symmetry b…
Are Glueballs Knotted Closed Strings?
Antti J. Niemi
Glueballs have a natural interpretation as closed strings in Yang-Mills theory. Their stability requires that the string carries a nontrivial twist, or then it is knotted. Since a…
Polynomial Invariants of Links in the Projective Space
Maciej Mroczkowski
The Homflypt and Kauffman skein modules of the projective space are computed. Both are free and generated by some infinite set of links. This set may be chosen to be L_n, where L_n…
On the galactic chemical evolution of sulfur
N. Ryde, D. L. Lambert
Sulfur abundances have been determined for ten stars to resolve a debate in the literature on the Galactic chemical evolution of sulfur in the halo phase of the Milky Way. Our anal…
Operations and single particle interferometry
Johan Aberg
Interferometry of single particles with internal degrees of freedom is investigated. We discuss the interference patterns obtained when an internal state evolution device is insert…
Geometry of decomposition dependent evolutions of mixed states
David Kult, Erik Sjöqvist
We examine evolutions where each component of a given decomposition of a mixed quantal state evolves independently in a unitary fashion. The geometric phase and parallel transport…
Threshold Perspectives on Meson Production
M. Wolke
Studies of meson production in nucleon-nucleon collisions at threshold are characterised by few degrees of freedom in a configuration of well defined initial and final states with…
Numerical simulation of the three-dimensional structure and dynamics of the non-magnetic solar chromosphere
Sven Wedemeyer, Bernd Freytag, Matthias Steffen +2
Three-dimensional numerical simulations with CO5BOLD, a new radiation hydrodynamics code, result in a dynamic, thermally bifurcated model of the non-magnetic chromosphere of the qu…
On Effective Actions for the Bosonic Tachyon
M. Smedbäck
We extend the analysis of hep-th/0304045 to the bosonic case and find the one-derivative effective action valid in the vicinity of rolling tachyons with an energy not larger than t…
Soft colour interactions and diffractive Higgs production
R. Enberg, G. Ingelman, N. Timneanu
The topical subject of Higgs production in diffractive hard scattering events at the Tevatron and LHC is discussed. This has been proposed as a Higgs discovery channel with appeali…
HE0107-5240, A Chemically Ancient Star.I. A Detailed Abundance Analysis
N. Christlieb, B. Gustafsson, A. J. Korn +5
We report a detailed abundance analysis for HE0107-5240, a halo giant with [Fe/H]_NLTE=-5.3. This star was discovered in the course of follow-up medium-resolution spectroscopy of e…
A measurement of the branching fractions of the b-quark into charged and neutral b-hadrons
The DELPHI Collaboration, J. Abdallah
The production fractions of charged and neutral b-hadrons in b-quark events from Z0 decays have been measured with the DELPHI detector at LEP. An algorithm has been developed, base…
Comment on "Memory Effects in an Interacting Magnetic Nanoparticle System"
M. Sasaki, P. E. Jönsson, H. Takayama +1
In Phys. Rev. Lett. 91 167206 (2003), Sun et al. study memory effects in an interacting nanoparticle system with specific temperature and field protocols. The authors claim that th…
Superparamagnetism and Spin Glass Dynamics of Interacting Magnetic Nanoparticle Systems
Petra E. Jönsson
The physical properties of magnetic nanoparticles have been investigated with focus on the influence of dipolar interparticle interaction. For weakly coupled nanoparticles, thermod…
Landauer conductance of tunnel junctions: Strong impact from boundary conditions
Peter Zahn, Ingrid Mertig
We present model calculations for the Landauer conductance of tunnel junctions. The tunneling of free electrons through a rectangular potential barrier is considered. The conductan…
The Supersymmetric Extension of the Faddeev model
Lisa Freyhult
We study the supersymmetric extension of the Faddeev model in four dimensions. The Faddeev model contains three dimensional soliton solutions and we are interested in how these sol…
Convection in the atmospheres and envelopes of Pre-Main Sequence stars
J. Montalban, F. D'Antona, F. Kupka +1
The Teff location of Pre-Main Sequence (PMS) evolutionary tracks depends on the treatment of over-adiabaticity. Since the convection penetrates into the stellar atmosphere, also th…
Optical Properties of Complex Dust Grains
A. C. Andersen, J. A. Sotelo, G. A. Niklasson +1
Dust particles in space may appear as clusters of individual grains. The morphology of these clusters could be of a fractal or more compact nature. To investigate how the cluster m…
Photoemission and the Electronic Structure of PuCoGa5
J. J. Joyce, J. M. Wills, T. Durakiewicz +6
The electronic structure of the first Pu based superconductor PuCoGa5 is explored using photoelectron spectroscopy and a novel theoretical scheme. Exceptional agreement between cal…
Nonquasiparticle states in half-metallic ferromagnet NiMnSb
L. Chioncel, M. I. Katsnelson, R. A. de Groot +1
Nonquasiparticle states above the Fermi energy are studied by first-principle dynamical mean field calculations for a prototype half-metallic ferromagnet, NiMnSb. We present a quan…
Optimal Topological Test for Degeneracies of Real Hamiltonians
Niklas Johansson, Erik Sjöqvist
We consider adiabatic transport of eigenstates of real Hamiltonians around loops in parameter space. It is demonstrated that loops that map to nontrivial loops in the space of eige…
Yang-Mills Duals for Semiclassical Strings
J. Engquist, J. A. Minahan, K. Zarembo
We consider a semiclassical multiwrapped circular string pulsating on S_5, whose center of mass has angular momentum J on an S_3 subspace. Using the AdS/CFT correspondence we argue…
