Nucleon structure in terms of OPE with non-perturbative Wilson coefficients
W. Bietenholz, N. Cundy, M. Gockeler +7
Lattice calculations could boost our understanding of Deep Inelastic Scattering by evaluating moments of the Nucleon Structure Functions. To this end we study the product of electr…
Perturbative determination of for plaquette and Symanzik gauge action and stout link clover fermions
R. Horsley, H. Perlt, P. E. L. Rakow +2
Using plaquette and Symanzik improved gauge action and stout link clover fermions we determine the improvement coefficient in one-loop lattice perturbation theory from the…
A status report of the QCDSF Project
Meinulf Göckeler, Roger Horsley, Yoshifumi Nakamura +8
We report about on-going simulations of lattice QCD. We use a tadpole improved Symanzik gauge action and stout link smeared Wilson fermions with a clover term. We employ…
Distribution Amplitudes of Vector Mesons
V. M. Braun, D. Brömmel, M. Göckeler +12
Results are presented for the lowest moment of the distribution amplitude for the K-star vector meson. Both longitudinal and transverse moments are investigated. We use two flavour…
An Abelian two-Higgs model and high temperature superconductivity
M. N. Chernodub, Arwed Schiller, E. -M. Ilgenfritz
We study a three dimensional Abelian Higgs model containing singly- and doubly-charged scalar fields coupled to a compact Abelian gauge field in the London limit. The model attract…
Embedded vortices and their interactions at electroweak crossover
M. N. Chernodub, E. -M. Ilgenfritz, A. Schiller
We study properties of Z-vortices in the crossover region of the 3D SU(2) Higgs model. Correlators of the vortex currents with gauge field energy and Higgs field squared ("quantum…
