Clusters of Galaxies: magnetic fields and nonthermal emission
H. J. Voelk, A. M. Atoyan
The nonthermal particle content of galaxy clusters should in part have a cosmological component generated during the early starburst phase of the member galaxies. This is reviewed…
The time structure of Cherenkov images generated by TeV gamma-rays and by cosmic rays
HEGRA Collaboration, M. Hess et al
The time profiles of Cherenkov images of cosmic-ray showers and of gamma-ray showers are investigated, using data gathered with the HEGRA system of imaging atmospheric Cherenkov te…
Hyperon Physics Results from SELEX
Ivo Eschrich
In parallel to charm hadroproduction the experiment SELEX (E781) at Fermilab is pursuing a rich hyperon physics program. SELEX employs a 600 GeV/c beam consisting of 50% Σ^- and π^…
The 3-D structure of the Virgo cluster from H band Fundamental Plane and Tully-Fisher distance determinations
G. Gavazzi, A. Boselli, M. Scodeggio +2
We undertook a surface photometry survey of 200 galaxies in the Virgo cluster (complete to B<14.0 mag) carried out in the near-Infrared (NIR) H band. Combining velocity dispersion…
Half-filled Landau level as a Fermi liquid of dipolar quasiparticles
A. Stern, B. I. Halperin, F. von Oppen +1
In this paper we study the relation between the conventional Fermion-Chern-Simons (FCS) theory of the half-filled Landau level (nu=1/2), and alternate descriptions that are based o…
Isophot Observations of Comet Hale-Bopp: Initial Data Reduction
E. Grün, S. B. Peschke, M. Stickel +17
Comet Hale-Bopp was observed five times with ISOPHOT, the photometer on board the Infrared Space Observatory (ISO). Each time broadband photometry was performed using 4 different d…
N=2 central charge superspace and a minimal supergravity multiplet
G. Akemann, R. Grimm, M. Hasler +1
We extend the notion of central charge superspace to the case of local supersymmetry. Gauged central charge transformations are identified as diffeomorphisms at the same footing as…
New limits on dark--matter WIMPs from the Heidelberg--Moscow experiment
L. Baudis, J. Hellmig, G. Heusser +12
New results after 0.69 kg yr of measurement with an enriched 76Ge detector of the Heidelberg--Moscow experiment with an active mass of 2.758 kg are presented. An energy threshold o…
Background and Technical Studies for GENIUS as a Dark Matter Experiment
L. Baudis, G. Heusser, B. Majorovits +3
The GENIUS project is a proposal for a new dark matter detector, with an increased sensitivity of three orders of magnitude relative to existing direct dark matter detection experi…
A Mesoscopic Quantum Eraser
G. Hackenbroich, B. Rosenow, H. A. Weidenmueller
Motivated by a recent experiment by Buks et al. [Nature 391, 871 (1998)] we consider electron transport through an Aharonov-Bohm interferometer with a quantum dot in one of its arm…
Observation of a Coherence Length Effect in Exclusive Rho^0 Electroproduction
K. Ackerstaff
Exclusive incoherent electroproduction of the rho^0(770) meson from 1H, 2H, 3He, and 14N targets has been studied by the HERMES experiment at squared four-momentum transfer Q**2>0.…
Properties of low-lying states in a diffusive quantum dot and Fock-space localization
Carlos Mejia-Monasterio, Jean Richert, Thomas Rupp +1
Motivated by an experiment by Sivan et al. (Europhys. Lett. 25, 605 (1994)) and by subsequent theoretical work on localization in Fock space, we study numerically a hierarchical mo…
Measurement of the Sigma^- Charge Radius at SELEX
Ivo Eschrich
The charge radii of Sigma^- and pi^- have been determined by direct elastic scttering on shell electrons. The measurement was performed in the framework of the SELEX (E781) charm h…
Universality of quantum Brownian motion
Eric Lutz, Hans A. Weidenmueller
Are Markovian master equations for quantum Brownian motion independent of model assumptions used in the derivation and, thus, universal? With the aim of answering this question, we…
Spectral correlations of the massive QCD Dirac operator at finite temperature
Burkhard Seif, Tilo Wettig, Thomas Guhr
We use the graded eigenvalue method, a variant of the supersymmetry technique, to compute the universal spectral correlations of the QCD Dirac operator in the presence of massive d…
A Comment on the Light-Cone Vacuum in 1+1 Dimensional Super-Yang-Mills Theory
F. Antonuccio, S. Pinsky, S. Tsujimaru
The Discrete Light-Cone Quantization (DLCQ) of a supersymmetric gauge theory in 1+1 dimensions is discussed, with particular attention given to the inclusion of the gauge zero mode…
Coupled Microwave Billiards as a Model for Symmetry Breaking
H. Alt, C. I. Barbosa, H. -D. Graef +5
Two superconducting microwave billiards have been electromagnetically coupled in a variable way. The spectrum of the entire system has been measured and the spectral statistics ana…
The Influence of Strong Interaction on the Pionium Wave Functions at Small Distances
I. Amirkhanov, I. Puzynin, A. Tarasov +2
The influence of strong interaction of the behaviour of pionium nS-state wave functions at small distance are investigated both analytically (perturbatively) and so numeri…
