Some Global Properties of the Attractive Hubbard Model in the Superconducting Phase: T-Matrix Approximation in 2D
S. Schafroth, J. J. Rodriguez, H. Beck
We have applied the Fast Fourier transform (FFT), which allows to compute efficiently convolution sums, to solve the set of self-consistent T-matrix equations to get the Green func…
Resonance Contributions to the Electromagnetic Low Energy Constants of Chiral Perturbation Theory
Robert Baur, Res Urech
The effective chiral Lagrangian of the strong and electromagnetic interactions of the pseudoscalar mesons at low energies depends on a set of low energy constants. We determine the…
Weak Radiative B-Meson Decay Beyond Leading Logarithms
Konstantin Chetyrkin, Mikolaj Misiak, Manfred Munz
We present our results for three-loop anomalous dimensions necessary in analyzing decay at the next-to-leading order in QCD. We combine them with other recently calcul…
Recent Developments in Seiberg-Witten Theory and Complex Geometry
Christian Okonek, Andrei Teleman
Recent developments in Seiberg-Witten theory and relations with Complex Geometry.
Thermodynamics of the two--dimensional O(3) non linear sigma model with Fixed-Point lattice action
S. P. Spiegel
We calculate the free energy density of the two dimensional O(3) non linear sigma model over a large temperature region. At high temperatures the calculations could be done by pert…

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…
On Symmetric Gauge Fields for arbitrary Gauge and Symmetry Groups
Othmar Brodbeck
A classification of the possible symmetric principal bundles with a compact gauge group, a compact symmetry group and a base manifold which is regularly foliated by the orbits of t…
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…
Finite Temperature Schwinger Model with Chirality Breaking Boundary Conditions
Stephan Dürr, Andreas Wipf
The -flavour Schwinger Model on a finite space and subject to bag-type boundary-conditions at und is solved at finite temperature . Th…
Search for Excited Fermions with the H1 Detector
S. Aid
We present a search for excited electrons, neutrinos and quarks using the H1 detector at the collider HERA, based on data taken in 1994 with an integrated luminosity of 2.75 p…
Inflation with a Complex Scalar Field
D. Scialom
We discuss the coupled Einstein-Klein-Gordon equations for a complex scalar field with and without a quartic self-interaction in a zero curvature Friedman-Lema\^ıtre Universe. The…
Two-Loop Diagrams in Causal Perturbation Theory
A. Aste, G. Scharf
The scalar two-loop master diagram is revisited in the massive cases needed for the computation of boson and fermion propagators in QED and QCD. By means of the causal method it is…
Charged Particle Multiplicities in Deep Inelastic Scattering at HERA
S. Aid
Using the H1 detector at HERA, charged particle multiplicity distributions in deep inelastic ep scattering have been measured over a large kinematical region. The evolution with $W…
Inclusive and Production in Deep Inelastic Collisions at HERA
S. Aid
First results on inclusive D0 and D* production in deep inelastic scattering are reported using data collected by the H1 experiment at HERA in 1994. Differential cross section…

M. Heusler
We establish the equality of the ADM mass and the total electric charge for asymptotically flat, static electrovac black hole spacetimes with completely degenerate, not necessarily…
Master Spaces for stable pairs
Christian Okonek, Alexander Schmitt, Andrei Teleman
We construct master spaces for oriented torsion free sheaves coupled with morphisms into a fixed reference sheaf. These spaces are projective varieties endowed with a natural $\C^*…
Slavnov-Taylor Identities from the Causal Point of View
Michael Duetsch
We continue the investigation of quantized Yang-Mills theories coupled to matter fields in the framework of causal perturbation theory which goes back to Epstein and Glaser. In thi…
Non-Uniqueness of Quantized Yang-Mills Theories
Michael Duetsch
We consider quantized Yang-Mills theories in the framework of causal perturbation theory which goes back to Epstein and Glaser. In this approach gauge invariance is expressed by a…
