Lattice calculation of the gluon propagator and the strangeness magnetic moment of the nucleon
Abstract
This contribution summarizes a presentation combining two topics in lattice QCD. Firstly, the gluon propagator in Landau gauge is calculated in quenched QCD on a large (323x64) lattice at beta=6.0. New structure seen in the infrared region survives conservative cuts to the lattice data, and serves to exclude a number of models that have appeared in the literature. Secondly, I report on a recent lattice QCD calculation of the strangeness magnetic moment of the nucleon. The result is GMs(0) =-0.36 +/- 0.20 . The strangeness Sachs electric mean-square radius was also found to be small and negative.
