Landau-Ginzburg Vacua of String, M- and F-Theory at c=12
Monika Lynker, Rolf Schimmrigk, Andreas Wisskirchen
Theories in more than ten dimensions play an important role in understanding nonperturbative aspects of string theory. Consistent compactifications of such theories can be construc…
Classical Limits of Euclidean Gibbs States for Quantum Lattice Models
Sergio Albeverio, Yuri Kondratiev, Yuri Kozitsky
Models of quantum and classical particles on the d-dimensional cubic lattice with pair interparticle interactions are considered. The classical model is obtained from the correspon…
Dynamics of SiO glasses
C. Oligschleger
Results on the dynamics of silica are presented: vibrations and relaxations. Using molecular dynamics, glass structures are generated by rapidly quenching melts below the glass tra…
Strong-coupling perturbation theory for the two-dimensional Bose-Hubbard model in a magnetic field
M. Niemeyer, J. K. Freericks, H. Monien
The Bose-Hubbard model in an external magnetic field is investigated with strong-coupling perturbation theory. The lowest-order secular equation leads to the problem of a charged p…
A Measurement of the tau->electron Branching Ratio
The OPAL Collaboration, G. Abbiendi et al
The branching ratio for the decay tau->e nue nutau has been measured using Z0 decay data collected by the OPAL experiment at LEP. In total 33073 tau->e nue nutau candidates were id…
Five-Dimensional Gauged Supergravity and Supersymmetry Breaking in ~Theory
John Ellis, Zygmunt Lalak, Witold Pokorski
We extend the formulation of gauged supergravity in five dimensions, as obtained by compactification of ~theory on a deformed Calabi-Yau manifold, to include non-universal matte…
Dynamical Correlation Functions using the Density Matrix Renormalization Group
Till D. Kuehner, Steven R. White
The density matrix renormalization group (DMRG) method allows for very precise calculations of ground state properties in low-dimensional strongly correlated systems. We investigat…
The associative algebras of conformal field theory
David Brungs, Werner Nahm
Modulo the ideal generated by the derivative fields, the normal ordered product of holomorphic fields in two-dimensional conformal field theory yields a commutative and associative…
Hydrostatics of the Galactic Halo
P. M. W. Kalberla, J. Kerp
We investigated a hydrostatic equilibrium model of the Milky Way following Parker (1966), to constrain the large scale properties of the interstellar medium. In our approach we fou…
The gaseous Milky Way Halo
P. M. W. Kalberla, J. Kerp
In 1998 several papers claim the detection of an ubiquitous gaseous phase within the Galactic halo. Here we like to focus on the detections of X-ray emitting gas within the Galacti…
HVCs probing a gaseous Galactic halo
P. M. W. Kalberla, J. Kerp, U. Haud
We study the hypothesis that high-velocity clouds (HVCs) may originate from instabilities within the gaseous phase of the Galactic halo. According to the hydrostatic equilibrium mo…
Soft X-rays from High-Velocity Clouds
J. Kerp, P. M. W. Kalberla, M. J. Freyberg +2
The ROSAT mission gave us the unique possibility to study the galactic interstellar medium by ``shadowing'' observations on arcmin angular resolution level. The high sensitivity of…
On the size of isospin violation in low-energy pion-nucleon scattering
Nadia Fettes, Ulf-G. Meißner, Sven Steininger
We present an analysis of isospin-breaking effects in threshold pion-nucleon scattering due to the light quark mass difference and the dominant virtual photon effects. We discuss t…
Finite-size energy levels of the superintegrable chiral Potts model
G. von Gehlen
In the solution of the superintegrable chiral Potts model special polynomials related to the representation theory of the Onsager algebra play a central role. We derive approximate…
Horizontal-Branch Stars: Their nature and their absolute magnitude
Klaas S. de Boer
Horizontal-branch stars play an important role in defining the absolute distance scale in the universe. For that one has to know Mv at relevant B-V with well defined [M/H] for each…
Billiard knots in a cylinder
Christoph Lamm, Daniel Obermeyer
We define cylinder knots as billiard knots in a cylinder. We present a necessary condition for cylinder knots: after dividing cylinder knots by possible rotational symmetries we ob…
Measurement of Three-jet Distributions in Photoproduction at HERA
ZEUS Collaboration
The cross section for the photoproduction of events containing three jets with a three-jet invariant mass of M_3J > 50 GeV has been measured with the ZEUS detector at HERA. The thr…
Comparison of triton bound state properties using different separable representations of realistic potentials
W. Schadow, W. Sandhas, J. Haidenbauer +1
The quality of two different separable expansion methods ({\sl W} matrix and Ernst-Shakin-Thaler) is investigated. We compare the triton binding energies and components of the trit…
Photoabsorption on nuclei in the shadowing threshold region
V. Muccifora, N. Bianchi, A. Deppman +10
The energy and nuclear mass dependences of the total hadronic cross section in the energy range 0.5-2.6 GeV have been measured at Bonn using the SAPHIR tagged photon beam. The meas…
The Cosmological Constant , the Age of the Universe and Dark Matter: Clues from the Ly-Forest
Carsten van de Bruck, Wolfgang Priester
Evidence for a positive cosmological constant , derived from the Ly-forest in high-resolution spectra of quasars, leads to a closed, low-density, -dominated universe. The…
A search for soft X-ray emission associated with prominent high-velocity-cloud complexes
J. Kerp, W. B. Burton, R. Egger +5
We correlate the ROSAT 1/4 keV all-sky survey with the Leiden/Dwingeloo HI survey, looking for soft X-ray signatures of prominent high-velocity-cloud (HVC) complexes. We study the…
The Gold Effect: Odyssey of Scientific Research
Wolfgang Kundt
Seventy-nine physical problems are listed and explained with whose proposed solutions I do not agree. Such disagreements -- even though some of them may simply reflect our prelimin…
Scattering and resonances in the ^4He three-atomic system
E. A. Kolganova, A. K. Motovilov
A mechanism of disappearance and formation of the Efimov levels of the helium ^4He_3 trimer is studied when the force of interatomic interaction is changed. The resonances includin…
Test of Time Reversal Invariance in Polarized Proton-Deuteron Scattering
TRI collaboration, J. Bisplinghoff, J. Ernst +7
A novel test of time-reversal invariance in proton-deuteron scattering is planned as an internal target transmission experiment at the cooler synchrotron COSY. The P-even, T-odd ob…
