Modelling Plerion Spectra and their Evolution
Yves A. Gallant, Eric van der Swaluw, John G. Kirk +1
We review recent theoretical developments on pulsar winds, their nebulae and relativistic shock acceleration, and show how they illuminate unsolved problems in plerion spectra, in…
TeV Blazars and Cosmic Infrared Background Radiation
F. A. Aharonian
The recent developments in studies of TeV radiation from blazars are highlighted and the implications of these results for derivation of cosmologically important information about…
Density Matrix of a Bose--Einstein Condensate: Steady--State versus Mean--Field Approach
S. J. Wang, M. C. Nemes, A. N. Salgueiro +1
We compare the equilibrium solution for the condensate obtained in the mean--field approximation to the master equation for sympathetic cooling with the one obtained by Scully for…
Sympathetic Cooling with Two Atomic Species in an Optical Trap
M. Mudrich, S. Kraft, K. Singer +3
We simultaneously trap ultracold lithium and cesium atoms in an optical dipole trap formed by the focus of a CO laser and study the exchange of thermal energy between the gases…
Symmetry Properties of the k-Body Embedded Unitary Ensemble of Random Matrices
Z. Pluhar, H. A. Weidenmueller
We extend the recent study of the k-body embedded Gaussian ensembles by Benet et al. (Phys. Rev. Lett. 87 (2001) 101601-1 and Ann. Phys. 292 (2001) 67) and by Asaga et al. (cond-ma…
On helicity and spin on the light cone
A. Krassnigg, Hans-Christian Pauli
Starting from a one-body front-form equation with Lepage-Brodsky spinors we show, with a fair amount of new technology, how an integral equation in standard momentum space with Bjo…
Mean-Field Approximation to the Master Equation for Sympathetic Cooling of Trapped Bosons
S. J. Wang, M. C. Nemes, A. N. Salgueiro +1
We use the mean-field approximation to simplify the master equation for sympathetic cooling of Bosons. For the mean single-particle occupation numbers, this approach yields the sam…
ISOPHOT - Photometric Calibration of Point Sources
B. Schulz, S. Huth, R. J. Laureijs +14
All observations by the aperture photometer (PHT-P) and the far-infrared (FIR) camera section (PHT-C) of ISOPHOT included reference measurements against stable internal fine calibr…
Renormalized QCD-inspired model for the pion and mesons
T. Frederico, M. Frewer, H. -C. Pauli
We apply the subtraction method to an effective QCD-inspired model, which includes the Coulomb plus a zero-range hyperfine interactions, to define a renormalized Hamiltonian for me…
Cold dust in late-type Virgo Cluster galaxies
Cristina C. Popescu, Richard J. Tuffs, Heinrich J. Voelk +2
We have statistically analyzed the spatially integrated far-infrared (FIR) emissions of the complete volume- and luminosity-limited sample of late-type (later than S0) Virgo cluste…
On the structure of the pion: A QCD--inspired point of view
Hans-Christian Pauli
The effective interaction between a quark and an anti-quark as obtained previously with by the method of iterated resolvents is replaced by the so called up-down-model and applied…
Renormalization of an effective model Hamiltonian by a counter term
Michael Frewer, Tobias Frederico, Hans-Christian Pauli
An ill-defined integral equation for modeling the mass-spectrum of mesons is regulated with an additional but unphysical parameter. This parameter dependance is removed by renormal…
Search for Excited Neutrinos at HERA
H1 Collaboration, C. Adloff
We present a search for excited neutrinos using e^-p data taken by the H1 experiment at HERA at a center-of-mass energy of 318 GeV with an integrated luminosity of 15 pb-1. No evid…
External Compton emission from relativistic jets in Galactic black hole candidates and ultraluminous X-ray sources
M. Georganopoulos, F. A. Aharonian, J. G. Kirk
Galactic binary systems that contain a black hole candidate emit hard X-rays in their low luminosity mode. We show that this emission can be understood as due to the Compton scatte…
Radiative decay width of the a2(1320)^- meson
The SELEX collaboration, V. V. Molchanov
Coherent pi^+pi^-pi^- production in the interactions of a beam of 600 GeV pi^- mesons with C, Cu and Pb nuclei has been studied with the SELEX facility (Experiment E781 at Fermilab…
Nuclear effects in the Drell-Yan process at very high energies
B. Z. Kopeliovich, J. Raufeisen, A. V. Tarasov +1
We study Drell-Yan (DY) dilepton production in proton(deuterium)-nucleus and in nucleus-nucleus collisions within the light-cone color dipole formalism. This approach is especially…
Sympathetic Cooling of Lithium by Laser-cooled Cesium
S. Kraft, M. Mudrich, K. Singer +3
We present first indications of sympathetic cooling between two neutral, optically trapped atomic species. Lithium and cesium atoms are simultaneously stored in an optical dipole t…
New Results on Pb-Au Collisions at 40 AGeV from the CERES/NA45 Experiment
K. Filimonov
In 1999 the CERES/NA45 ran at the CERN SPS with a beam energy of 40 GeV/nucleon. The data set comprises about 8.7 millions Pb-Au events with a trigger selection corresponding to ap…

Borexino Collaboration, C. Arpesella
The techniques researched, developed and applied towards the measurement of radioisotope concentrations at ultra-low levels in the real-time solar neutrino experiment BOREXINO at G…
Hadronic Production of Lambda_c from 600 GeV/c pion, sigma and proton beams
SELEX Collaboration, Fernanda G. Garcia
We present data from Fermilab experiment E781 (SELEX) on the hadroproduction asymmetry for anti-Lambda_c compared to Lambda_c+ as a function of xF and pt2 distributions for Lambda_…

Using data from the HEGRA air shower array, taken in the period from April 1998 to March 2000, upper limits on the ratio I_gamma /I_CR of the diffuse photon flux I_gamma to the had…
Partition Functions in Statistical Mechanics, Symmetric Functions, and Group Representations
A. B. Balantekin
Partition functions for non-interacting particles are known to be symmetric functions. It is shown that powerful group-theoretical techniques can be used not only to derive these r…
