Comparison of topological charge definitions in Lattice QCD
Constantia Alexandrou, Andreas Athenodorou, Krzysztof Cichy +5
In this paper, we show a comparison of different definitions of the topological charge on the lattice. We concentrate on one small-volume ensemble with 2 flavours of dynamical, max…
A Mixed Action Analysis of and Mesons
Konstantin Ottnad, Carsten Urbach, Falk Zimmermann
We study and mesons and their mixing angle in a mixed action approach with so-called Osterwalder-Seiler valence quarks on a Wilson twisted mass sea. The gauge configuratio…
Comparison of different lattice definitions of the topological charge
Krzysztof Cichy, Arthur Dromard, Elena Garcia-Ramos +5
We present a comparison of different definitions of the topological charge on the lattice, using a small-volume ensemble with 2 flavours of dynamical twisted mass fermions. The inv…
Investigating a mixed action approach for η and η' mesons in Nf=2+1+1 lattice QCD
Konstantin Ottnad, Carsten Urbach, Falk Zimmermann
We present results for a test of a mixed action approach with Osterwalder-Seiler valence quarks on a Wilson twisted mass sea for the example η, η' mesons. Flavour singlet pseudosca…
Testing the stochastic LapH method in the twisted mass formulation
Christian Jost, Bastian Knippschild, Carsten Urbach +1
We present first results using the stochastic Laplace-Heaviside (sLapH) method in the twisted mass formulation. The calculations are performed on gauge configurations provided by t…
Properties of pseudoscalar flavour-singlet mesons from 2+1+1 twisted mass lattice QCD
Krzysztof Cichy, Vincent Drach, Elena Garcia-Ramos +5
We study properties of pseudoscalar flavour-singlet mesons from Wilson twisted mass lattice QCD with Nf=2+1+1 dynamical quark flavors. Results for masses are presented at three val…
Vacuum structure and string tension in Yang-Mills dimeron ensembles
Falk Zimmermann, Hilmar Forkel, Michael Muller-Preussker
We numerically simulate ensembles of SU(2) Yang-Mills dimeron solutions with a statistical weight determined by the classical action and perform a comprehensive analysis of their p…
