Searching for KvBLL calorons in SU(3) lattice gauge field ensembles
Christof Gattringer, Ernst-Michael Ilgenfritz, Boris V. Martemyanov +5
We discuss Kraan - van Baal - Lee - Lu (KvBLL) solutions of the classical Yang-Mills equations with temperature in the context of SU(3) lattice gauge theory. We present discretized…
Low-Lying Nucleons from Chirally Improved Fermions
D. Broemmel, P. R. Crompton, C. Gattringer +4
We report on our preliminary results on the low-lying excited nucleon spectra which we obtain through a variational basis formed with three different interpolators.
Excited nucleons with chirally improved fermions
Dirk Broemmel, Peter Crompton, Christof Gattringer +4
We study positive and negative parity nucleons on the lattice using the chirally improved lattice Dirac operator. Our analysis is based on a set of three operators chi_i with the n…
Quenched spectroscopy with fixed-point and chirally improved fermions
BGR Collaboration, Christof Gattringer, Meinulf Gockeler +10
We present results from quenched spectroscopy calculations with the parametrized fixed-point and the chirally improved Dirac operators. Both these operators are approximate solutio…
A lattice calculation of vector meson couplings to the vector and tensor currents using chirally improved fermions
V. M. Braun, T. Burch, C. Gattringer +4
We present a quenched lattice calculation of , the coupling of vector mesons to the tensor current normalized by the vector meson decay constant. The chirally improv…
New findings for topological excitations in SU(3) lattice gauge theory
Christof Gattringer, Stefan Schaefer
We probe the SU(3) vacuum using eigenvectors of the Dirac operator with an arbitrary phase for the temporal boundary condition. We consider configurations with topological charge |…
