Generalized perton distributions: analysis and applications
P. Kroll
Results from a recent analysis of the zero-skewness generalized parton distributions (GPDs) for valence quarks are discussed. The analysis bases on a physically motivated parameter…
Search for extraterrestrial point sources of high energy neutrinos with AMANDA-II using data collected in 2000-2002

The results of a search for point sources of high energy neutrinos in the northern hemisphere using data collected by AMANDA-II in the years 2000, 2001 and 2002 are presented. In p…
Ultra High Energy nu_tau detection at Pierre Auger Observatory
G. Miele, L. Perrone, O. Pisanti
Earth--skimming UHE tau neutrinos have a chance to be detected by the Fluorescence Detector (FD) of Pierre Auger Observatory if their astrophysical flux is large enough. A detailed…
Integral representation of the density matrix of the XXZ chain at finite temperatures
Frank Göhmann, Andreas Klümper, Alexander Seel
We present an integral formula for the density matrix of a finite segment of the infinitely long spin-1/2 XXZ chain. This formula is valid for any temperature and any longitudinal…
Reduced qKZ equation and correlation functions of the XXZ model
H. Boos, M. Jimbo, T. Miwa +2
Correlation functions of the XXZ model in the massive and massless regimes are known to satisfy a system of linear equations. The main relations among them are the difference equat…
A Search for Anomalous Heavy-Flavor Quark Production in Association with W Bosons

S. V. Goloskokov, P. Kroll
It is reported on an analysis of vector meson leptoproduction at small Bjorken- and large photon virtuality within an approach that bases on generalized parton distributions (GP…
Framed quiver moduli, cohomology, and quantum groups
Markus Reineke
Framed quiver moduli parametrize stable pairs consisting of a quiver representation and a map to a fixed graded vector space. Geometric properties and explicit realizations of fram…
Lattice QCD with two dynamical flavors of domain wall quarks
Y. Aoki, T. Blum, N. Christ +11
We present results from the first large-scale study of two flavor QCD using domain wall fermions (DWF), a chirally symmetric fermion formulation which has proven to be very effecti…
Scaling tests with dynamical overlap and rooted staggered fermions
Stephan Dürr, Christian Hoelbling
We present a scaling analysis in the 1-flavor Schwinger model with the full overlap and the rooted staggered determinant. In the latter case the chiral and continuum limit of the s…
Formation of clusters in the ground state of the model on a two leg ladder
A. Fledderjohann, A. Langari, K. -H. Muetter
We investigate the ground state properties of the model on a two leg ladder with anisotropic couplings () along rungs and () along legs. We have impleme…
