Hard Single Diffraction in pbarp Collisions at root-s = 630 and 1800 GeV
The D0 Collaboration, B. Abbott
Using the D0 detector, we have studied events produced in proton-antiproton collisions that contain large forward regions with very little energy deposition (``rapidity gaps'') and…
Target-Space Duality in Heterotic and Type I Effective Lagrangians
Zygmunt Lalak, Stéphane Lavignac, Hans Peter Nilles
We study the implications of target-space duality symmetries for low-energy effective actions of various four-dimensional string theories. In the heterotic case such symmetries can…
Dipole moments of the Electron, Neutrino and Neutron in the MSSM without R-parity Symmetry
S. A. Abel, A. Dedes, H. K. Dreiner
We show that in the MSSM without R-parity symmetry there are no new contributions to electron and neutron electric dipole moments (EDMs) at 1-loop induced by the R-parity violating…
Soft Gamma-ray Repeaters in Clusters of Massive Stars
Felix I. Mirabel, Yael Fuchs, and Sylvain Chaty
Infrared observations of the environment of the two Soft Gamma-ray Repeaters (SGRs) with the best known locations on the sky show that they are associated to clusters of massive st…
Cosmic Statistics of Statistics
I. Szapudi, S. Colombi, F. Bernardeau
The errors on statistics measured in finite galaxy catalogs are exhaustively investigated. The theory of errors on factorial moments by Szapudi & Colombi (1996) is applied to cumul…
Smoke in the "Smoke Rings": ISO Observations of Dust in Collisional Ring Galaxies
P. N. Appleton, V. Charmandaris, C. Horellou +2
Collisional ring galaxies probably result from a head-on collision between a compact companion galaxy and a gas-rich disk system. We present a review of the discovery of warm dust…
The Isolated Photon Cross Section in p pbar Collisions at sqrt(s) = 1.8 TeV
D0 Collaboration, B. Abbott
We report a new measurement of the cross section for the production of isolated photons, with transverse energies (ET) above 10 GeV and pseudorapidities |eta| < 2.5, in p pbar coll…
The ratio of proton's electric to magnetic form factors measured by polarization transfer
The Jefferson Lab Hall A Collaboration, M. K. Jones
The ratio of the proton's elastic electromagnetic form factors was obtained by measuring the transverse and longitudinal polarizations of recoiling protons from the elastic scatter…
The Robustness of Quintessence
Philippe Brax, Jerome Martin
Recent observations seem to suggest that our Universe is accelerating implying that it is dominated by a fluid whose equation of state is negative. Quintessence is a possible expla…
A Measurement of the W to tau+nu Production Cross Section in p-pbar Collisions at sqrt(s) = 1.8 TeV
D0 Collaboration, B. Abbott
We report on a measurement of sigma(p-pbar to W+X) times B(W to tau+nu) in p-pbar collisions at sqrt(s) = 1.8 TeV at the Fermilab Tevatron. The measurement is based on an integrate…
Limits on Anomalous WWgamma and WWZ Couplings from WW/WZ->enujj Production
D0 collaboration, B. Abbott, M. Abolins
Limits on anomalous WWgamma and WWZ couplings are presented from a study of WW/WZ->enujj events in ppbar collisions at sqrt{s}=1.8 TeV. Results from the analysis of data collected…
Probing BFKL Dynamics in the Dijet Cross Section at Large Rapidity Intervals in ppbar Collisions at sqrt{s}=1800 and 630 GeV
D0 Collaboration, B. Abbott
Inclusive dijet production at large pseudorapidity intervals (delta_eta) between the two jets has been suggested as a regime for observing BFKL dynamics. We have measured the dijet…
Limits on Quark Compositeness from High Energy Jets in PbarP Collisions at 1.8 TeV
D0 collaboration, B. Abbott
Events in PbarP collisions at sqrt(s)=1.8 TeV with total transverse energy exceeding 500 GeV are used to set limits on quark substructure. The data are consistent with next-to-lead…
Conformal field theory and edge excitations for the principal series of quantum Hall fluids
V. Pasquier, D. Serban
Motivated by recent experimental results, we reconsider the theory of the edge excitations for the fractional Hall effect at filling factors . We propose to modify the…
Dynamics of the Local Moment Induced by Nonmagnetic Defects in Cuprates
W. A. MacFarlane, J. Bobroff, H. Alloul +4
We present a study of the spin dynamics of magnetic defects induced by Li substitution of the plane Cu in the normal state of YBaCuO. The fluctuations of the couple…
Sunyaev-Zel'dovich Effect Derived Distances to the High Redshift Clusters MS 0451.6-0305 and CL 0016+16
E. D. Reese, J. J. Mohr, J. E. Carlstrom +7
We determine the distances to the z~0.55 galaxy clusters MS 0451.6-0305 and CL 0016+16 from a maximum likelihood joint fit to interferometric Sunyaev-Zel'dovich effect (SZE) and X-…
XEUS - The X-ray Evolving Universe Spectroscopy Mission
A. N. Parmar, T. Peacock, M. Bavdaz +19
XEUS is under study by ESA as part of the Horizon 2000+ program to utilize the International Space Station (ISS) for astronomical applications. XEUS will be a long-term X-ray obser…
Non-ohmic hopping transport in a-YSi: from isotropic to directed percolation
F. Ladieu, D. L'Hôte, R. Tourbot
Variable range hopping transport has been investigated in amorphous YSi from 30 mK to 2 K as a function of the temperature T and electric field F. For F=0, where conduction is alon…
Response of non-equilibrium systems at criticality: Exact results for the Glauber-Ising chain
C. Godreche, J. M. Luck
We investigate the non-equilibrium two-time correlation and response functions and the associated fluctuation-dissipation ratio for the ferromagnetic Ising chain with Glauber dynam…
U(1) Problem at Finite Temperature
Romuald A. Janik, Maciej A. Nowak, Gabor Papp +1
We model the effects of a large number of zero and near-zero modes in the QCD partition function by using sparse chiral matrix models with an emphasis on the quenched topological s…

Brian D. Fields, Keith A. Olive, Elisabeth Vangioni-Flam +1
The nucleosynthesis of Be and B by spallation processes provides unique insight into the origin of cosmic rays. Namely, different spallation schemes predict sharply different trend…
