Mass spectrum and decay constants in the continuum limit
M. Goeckeler, R. Horsley, V. Linke +6
We present first results for light hadron masses, quark masses and decay constants in the continuum limit using O(a) improved fermions at three different values of the gauge coupli…
Renormalization of four-fermion operators for higher twist calculations
S. Capitani, M. Göckeler, R. Horsley +4
The evaluation of the higher twist contributions to Deep Inelastic Scattering amplitudes involves a non trivial choice of operator bases for the higher orders of the OPE expansion…
Nucleon form factors and O(a) Improvement
S. Capitani, M. Gockeler, R. Horsley +9
Nucleon form factors have been extensively studied both experimentally and theoretically for many years. We report here on new results of a high statistics quenched lattice QCD cal…
Embedded Topological Defects in Electroweak Theory: From Percolating Networks to Sphalerons
M. N. Chernodub, F. V. Gubarev, E. -M. Ilgenfritz +1
New defects (Z-vortices and Nambu monopoles) are found to become thermodynamically relevant for the broken phase near to the (weakly first order) electroweak phase transition, and…
Composite operators in lattice QCD: nonperturbative renormalization
M. Gockeler, R. Horsley, H. Oelrich +6
We investigate the nonperturbative renormalization of composite operators in lattice QCD restricting ourselves to operators that are bilinear in the quark fields. These include ope…
Simplicial Quantum Gravity on a Randomly Triangulated Sphere
Christian Holm, Wolfhard Janke
We study 2D quantum gravity on spherical topologies employing the Regge calculus approach with the dl/l measure. Instead of the normally used fixed non-regular triangulation we stu…
