Determination of the Longitudinal Proton Structure Function F_L(x,Q^2) at Low x
C. Adloff
A measurement of the inclusive cross section for the deep-inelastic scattering of positrons off protons at HERA is presented at momentum transfers and…
Spherical accretion onto neutron stars and black holes
L. Titarchuk, A. Mastichiadis, N. D. Kylafis
Spectral formation in steady state, spherical accretion onto neutron stars and black holes is examined by solving numerically and analytically the equation of radiative transfer. T…
Constraints on the VHE Emissivity of the Universe from the Diffuse GeV Gamma-Ray Background
P. S. Coppi, F. A. Aharonian
VHE (Very High Energy, E>100 GeV) radiation emitted at cosmological distances will pair produce on low-energy diffuse extragalactic background radiation before ever reaching us. Th…
Electroproduction of vector mesons off nuclei at ELFE: exact solution for color transparency
J. Hüfner, B. Z. Kopeliovich
A multichannel evolution equation is developed for the density matrix describing a hadronic wave packet produced by a virtual photon and propagation through a nuclear matter. This…
Measurement of Charged Particle Transverse Momentum Spectra in Deep Inelastic Scattering
C. Adloff, H1 Collaboration
Transverse momentum spectra of charged particles produced in deep inelastic scattering are measured as a function of the kinematic variables x_B and Q2 using the H1 detector at the…
Measurement of the proton and deuteron structure functions, F2p and F2d, and of the ratio sigma(L)/sigma(T)
The New Muon Collaboration
The muon-proton and muon-deuteron inclusive deep inelastic scattering cross sections were measured in the kinematic range 0.002 < x < 0.60 and 0.5 < Q2 < 75 GeV2 at incident muon e…
Variability in the synchrotron self-Compton model of blazar emission
A. Mastichiadis, J. G. Kirk
We present a model of the spectra of gamma-ray emitting blazars in which a single homogeneous emission region both emits synchrotron photons directly and scatters them to high (gam…
Masses of the physical mesons from an effective QCD--Hamiltonian
H. C. Pauli, J. Merkel
The front form Hamiltonian for quantum chromodynamics, reduced to an effective Hamiltonian acting only in the space, is solved approximately. After coordinate transformat…
Chaotic Scattering with Resonance Enhancement
B. Elattari, V. Kagalovsky, H. A. Weidenmueller
The passage of light or of electrons through a disordered medium is modified in the presence of resonances. We describe a simple model for this problem, and present first results.
Solving Gauge Field Theory by Discretized Light-Cone Quantization
Hans-Christian Pauli
The canonical front form Hamiltonian for non-Abelian SU(N) gauge theory in 3+1 dimensions is mapped on an effective Hamiltonian which acts only in the Fock space of one quark and o…
Superlight neutralino as a dark matter particle candidate
V. A. Bednyakov, S. G. Kovalenko, H. V. Klapdor-Kleingrothaus
We address the question of how light can be the lightest supersymmetric particle neutralino to be a reliable cold dark matter (CDM) particle candidate. To this end we have performe…
Baryon Asymmetry of the Proton Sea at Low
B. Z. Kopeliovich, B. Povh
We predict a nonvanishing baryon asymmetry of the proton sea at low . It is expected to be about and nearly -independent at . The asymmetry aris…
Interplay of Soft and Hard Interactions in Nuclear Shadowing at High and Low x
B. Z. Kopeliovich, B. Povh
Nuclear shadowing corrections are dominated by soft interaction and grow as function of more slowly than the single scattering term, which has an essential contribution from…
Inelastic Photoproduction off Nuclei: Gluon Enhancement or Double Color Exchange?
J. Huefner, B. Z. Kopeliovich, Al. B. Zamolodchikov
The nuclear enhancement observed in inelastic photoproduction of should not be interpreted as evidence for an increased gluon density in nuclei. The nuclear suppression of th…
Interplay of Interference Effects in Production of and off Nuclei
Joerg Huefner, Boris Kopeliovich
Our main observations are: (i) The effective path length of the wave packet, which is produced in the nucleus, grows with the energy of the produced charmonium. The varia…
The Nuclear Liquid-Gas Phase Transition: Present Status and Future Perspectives
J. Pochodzalla, ALADIN collaboration
More than two decades ago, the van der Waals behavior of the nucleon - nucleon force inspired the idea of a liquid-gas phase transition in nuclear matter. Heavy-ion reactions at re…

D. Petry, S. M. Bradbury, A. Konopelko +1
A detection of Gamma-rays from Mkn 421 at energies above 1 TeV is reported, based on observations made in December 1994 - May 1995 with the first two HEGRA Cherenkov telescopes. >F…
Is SUSY accessible by direct dark matter detection?
V. A. Bednyakov, S. G. Kovalenko, H. V. Klapdor-Kleingrothaus +1
We performed a combined analysis of the parameter space of the Minimal Supersymmetric Standard Model (MSSM) taking into account cosmological and accelerator constraints including t…
TeV emission from SN 1006
A. Mastichiadis, O. C. de Jager
Supernova 1006 is the first shell type supernova remnant to show evidence of particle acceleration to TeV energies. In the present paper we examine this possibility by modeling the…
