On The Instanton Solutions Of The Self-Dual Membrane In Various Dimensions
E. G. Floratos, G. K. Leontaris, A. P. Polychronakos +1
We present some methods of determining explicit solutions for self-dual supermembranes in 4+1 and 8+1 dimensions with spherical or toroidal topology. For configurations of axial sy…
Unification of Spectral States of Accreting Black Holes
Juri Poutanen, Paolo Coppi
Several galactic black holes show transitions between spectral states. In this paper we present a unifying radiation transfer model that can fit the spectral data in both states. W…
Neutralino relic density including coannihilations
Paolo Gondolo, Joakim Edsjo
We give an overview of our precise calculation of the relic density of the lightest neutralino, in which we included relativistic Boltzmann averaging, subthreshold and resonant ann…
Polarised Quark Distributions in the Nucleon from Semi-Inclusive Spin Asymmetries
Spin Muon Collaboration
We present a measurement of semi-inclusive spin asymmetries for positively and negatively charged hadrons from deep inelastic scattering of polarised muons on polarised protons and…
An SPH code for galaxy formation problems; Presentation of the code
John Hultman, Daniel Kaellander
We present and test a code for two-fluid simulations of galaxy formation, one of the fluids being collision-less. The hydrodynamical evolution is solved through the SPH method whil…
Rare decays of η-meson: the background of ρ- and ω- mesons
S. Kullander, H. Calén, K. Fransson +7
The problem of - and - mesons contributions to the background for decay and to the asymmetries in the decays and is consider…
Report of the Working Group on Goldstone Boson Production and Decay
J. Bijnens, G. Colangelo, G. D'Ambrosio +11
This is the summary of the working group on Goldstone Boson Production and Decay of the Chiral Dynamics Workshop in Mainz, September 1-5, 1997. For the production aspects we discus…
Abundances in metal-rich stars - Detailed abundance analysis of 47 G and K dwarf stars with [Me/H] 0.10 dex
Sofia Feltzing, Bengt Gustafsson
We have derived elemental abundances of O, Na, Mg, Al, Si, Ca, Ti, Cr, Mn, Fe, Co, Ni for 47 G and K dwarf, with [Me/H]>0.1 dex. The selection of stars was based on their kinematic…
Bound and Unbound Wave Functions at Short Distances
Goeran Faeldt, Colin Wilkin
There exists a simple relationship between a quantum-mechanical bound-state wave function and that of nearby scattering states, when the scattering energy is extrapolated to that o…
Near-infrared narrow-band photometry of M-giant and Mira stars: models meet observations
R. Alvarez, B. Plez
From near-infrared, narrow-band photometry of 256 oxygen-rich Mira variables we obtain evidence about the loops that these stars follow in colour-colour diagrams. We also find a ph…
Creation of Strings in D-particle Quantum Mechanics
Ulf H. Danielsson, Gabriele Ferretti
D-particle quantum mechanics in a type I' background is reviewed. It is also discussed how a string is created when a D-particle is taken through a D8-brane. The process is found t…
An explanation of the ABC enhancement in the dd -> alpha X reaction at intermediate energies
A. Gardestig, G. Faldt, C. Wilkin
The dd -> alpha X reaction is studied in a model where each pair of nucleons in the projectile and target deuterons undergoes pion production through the NN -> d pi reaction. The c…
Geometry of the BFV Theorem
K. Bering
We describe gauge-fixing at the level of virtual paths in the path integral as a non-symplectic BRST-type of flow on the path phase space. As a consequence a gauge-fixed, non-local…
Unified description of the non-singlet spin dependent structure function incorporating Altarelli-Parisi evolution and the double logarithmic effects at low
B. Badełek, J. Kwieciński
A unified equation for the non-singlet spin dependent structure function which incorporates the complete leading order Altarelli-Parisi evolution at finite an…
Lambda Hyperons in 2 A*GeV Ni + Cu Collisions
EOS Collaboration, M. Justice, S. Albergo +45
A sample of Lambda's produced in 2 A*GeV Ni + Cu collisions has been obtained with the EOS Time Projection Chamber at the Bevalac. Low background in the invariant mass distribution…
Superfield Quantization
I. A. Batalin, K. Bering, P. H. Damgaard
We present a superfield formulation of the quantization program for theories with first class constraints. An exact operator formulation is given, and we show how to set up a phase…
Determination of the universality class of Gadolinium
E. Frey, F. Schwabl, S. Henneberger +4
We resolve a longstanding puzzle for the static and dynamic critical behavior of Gadolinium by a combined theoretical and experimental investigation. It is shown that the spin dyna…
Measurement of the pbar p -> Ks Ks Reaction from 0.6 to 1.9 GeV/c
C. Evangelista, A. Palano, D. Drijard +40
The pbar p -> Ks Ks -> 4pi+/- cross section was measured at incident antiproton momenta between 0.6 and 1.9 GeV/c using the CERN Low Energy Antiproton Ring (LEAR). This investigati…
Physical Characteristics of the Spectral States of Galactic Black Holes
Juri Poutanen, Julian H. Krolik, Felix Ryde
Using simple analytical estimates we show how the physical parameters characterizing different spectral states of the galactic black hole candidates can be determined using spectra…
The rise and fall of the NaMgAl stars
Jocelyn Tomkin, Bengt Edvardsson, David L. Lambert +1
We have made new abundance determinations for a sample of NaMgAl stars. These stars, which are a subgroup of the nearby metal-rich field F and G disk dwarfs, were first identified…
Splitting of Landau levels of a 2D electron due to electron-phonon interactions
V. V. Cheianov, A. P. Dmitriev, V. Yu. Kachorovskii
We show that in a very strong magnetic field electron-phonon interaction gives rise to a splitting of Landau levels of a 2D electron into a series of infinitely degenerate subl…
Two-phase spectral modelling of 1E1740.7-2942
O. Vilhu, J. Nevalainen, J. Poutanen +5
Combined ASCA and SIGMA data of 1E1740.7-2942 during the standard state (September 1993 and 1994) were fitted with two-phase models (ISMBB/Poutanen at al. and ADAF/Narayan et al.).…
