Heavy-light baryonic mass splittings from the lattice
C. Alexandrou, A. Borrelli, S. Guesken +4
We present lattice estimates of the mass of the heavy-light baryons and obtained using propagating heavy quarks. For our result is $M_{Λ_b}=5.728 \pm 0.144 \pm 0.…
Effective Scalar Theory of the Electroweak Phase Transition
F. Karsch, T. Neuhaus, A. Patkós
This talk summarizes results obtained from simulating a three dimensional pure Order Parameter (OP) model of the Electroweak Phase Transition (EWPT). Its detailed presentation appe…
Anisotropic Gauge Theories: A Numerical Study of the Fu-Nielsen Model
Arjan Hulsebos
We study numerically 4+1 dimensional pure gauge theory.
Topological Updating Schemes: A Case Study In 3-d U(1)
Arjan Hulsebos, Peer Ueberholz
We study a topological updating scheme in three dimensional U(1) gauge theory. Some expectations for four dimensional SU(N) gauge theories are discussed.
New algorithm for gauge fixing in SU(2) lattice gauge theory
G. S. Bali, V. Bornyakov, M. Müller-Preussker +1
An overrelaxed variant of simulated annealing is applied to the problem of maximally abelian gauge fixing. The superiority of this algorithm over the commonly used relaxation proce…
Spin dependent potentials from SU(2) gauge theory
G. S. Bali, K. Schilling, A. Wachter
We present results on spin dependent potentials from lattice simulations of SU(2) gauge theory. The Coulomb like short range part of the central potential is identified as a mixed…
Monte Carlo Simulations of Off-Lattice Polymers
Peter Grassberger, Rainer Hegger
We point out that a newly introduced recursive algorithm for lattice polymers has a much wider range of applicability. In particular, we apply it to the simulation of off-lattice p…
Topological time series analysis of a string experiment and its synchronized model
Nicholas B. Tufillaro
Template and prunning front are calculated for an experimental chaotic time series from a mechanical string experiment. An empirical synchronized model is also created for the data…
Static Structure Factors of the XXZ-Model in the presence of a uniform field
M. Karbach, K. -H. Mütter, M. Schmidt
The static structure factors of the XXZ model in the presence of uniform field are determined from an exact computation of the groundstates at given total spin on rings with $N=4,6…
Meson-Photon Transition Form Factors
R. Jakob, P. Kroll, M. Raulfs
We report results on the - transition form factor obtained within the hard scattering approach including transverse momentum effects and Sudakov corrections. The results clea…
Self Avoiding Walks in Four Dimensions: Logarithmic Corrections
Peter Grassberger, Rainer Hegger, Lothar Schaefer
We present simulation results for long () self-avoiding walks in four dimensions. We find definite indications of logarithmic corrections, but the data are poorly descr…
Simulations of Single Polymer Chains in the Dense Limit
Peter Grassberger, Rainer Hegger
We present simulation results for single a-thermal chain polymers in finite volumes. For this we use a recently proposed recursive implementation of the enrichment method. In 3 dim…
Are Damage Spreading Transitions Generically in the Universality Class of Directed Percolation?
Peter Grassberger
We present numerical evidence for the fact that the damage spreading transition in the Domany-Kinzel automaton found by Martins {\it et al.} is in the same universality class as di…
Mean Field Behaviour in a Local Low-Dimensional Model
Hans-Martin Broeker, Peter Grassberger
We point out a new mechanism which can lead to mean field type behaviour in nonequilibrium critical phenomena. We demonstrate this mechanism on a two-dimensional model which can be…

G. S. Bali, K. Schilling, C. Schlichter
We present results of a high statistics study of the chromo field distribution between static quarks in SU(2) gauge theory on lattices of volumes 16^4, 32^4, and 48^3*64, with phys…
Beautiful Baryons from Lattice QCD
C. Alexandrou, A. Borrelli, S. Güsken +4
We perform a lattice study of heavy baryons, containing one () or two -quarks (). Using the quenched approximation we obtain for the mass of $$ M_{Λ_b}= 5.728 \p…
Intrinsic Transverse Size Effect
J. Bolz, R. Jakob, P. Kroll +2
Two recently proposed concepts to improve the perturbative calculation of exclusive amplitudes, gluonic radiative corrections (Sudakov factor) and confinement size effects (intrins…

Rainer Jakob
Independent multiple scattering (`Landshoff') contributions to proton-proton elastic scattering at wide angles are calculated in the quark-diquark model. Results confirm previous o…
Gauge Theories with a Layered Phase

We study abelian gauge theories with anisotropic couplings in dimensions. A layered phase is present, in the absence as well as in the presence of fermions. A line of second…

J. Bolz, R. Jakob, P. Kroll +2
The behavior of the proton magnetic form factor is studied within the modified hard scattering picture, which takes into account gluonic radiative corrections in terms of transvers…
