Excited hadrons on the lattice - State of the art and future challenges
Christof Gattringer
We review the techniques of lattice QCD calculations for excited hadrons with light quarks and outline the future challenges that are faced in calculations with fully dynamical fer…
Remarks on left-handed lattice fermions
Christof Gattringer, Markus Pak
We study whether applying lattice projectors on a vector-like Ginsparg-Wilson Dirac operator is the only way to construct left-handed lattice fermions. Using RG transformations we…
Fermion loop simulations in 2--d lattice theories -- results and limitations
Markus Limmer, Christof Gattringer, Verena Hermann
We review our results for the simulation of the 2--d lattice Gross--Neveu model in a fermion loop representation. Possible extensions of our techniques to other models and higher d…
Excited State Spectroscopy in the Lattice Gross-Neveu Model
Julia Danzer, Christof Gattringer
We present preliminary results of an excited state spectroscopy calculation in the 2-d lattice Gross-Neveu model. We address the construction of suitable interpolators for the vari…
Thin and dressed Polyakov loops from spectral sums of lattice differential operators
Erek Bilgici, Christian Hagen, Falk Bruckmann +1
We represent thin and dressed Polyakov loops as spectral sums of eigenvalues of differential operators on the lattice. For that purpose we calculate complete sets of eigenvalues of…
Dynamical Chirally Improved Quarks: First Results for Hadron Masses
R. Frigori, Ch. Gattringer, C. B. Lang +4
We present first results for a study with two mass-degenerate dynamical Chirally Improved (CI) fermions on lattices of spatial extent 2.4 fm. The CI Dirac operator obeys the Ginspa…
