Excited mesons from dynamical Clover Wilson lattices
Tommy Burch, Christian Hagen, Andreas Schäfer
We study mesons on the lattice with a special focus on excited states. For that purpose we construct several quark sources with different spatial smearings, including p-waves. Thes…
Improvement of quark propagator estimation through domain decomposition
Tommy Burch, Christian Hagen
Applying domain decomposition to the lattice Dirac operator and the associated quark propagator, we arrive at expressions which, with the proper insertion of random sources therein…

Search for the Theta^+(1540) in lattice QCD
Christian Hagen, Dieter Hierl, Andreas Schäfer
We report on a study of the pentaquark Theta^+(1540), using a variety of different interpolating fields. We use Chirally Improved fermions in combination with Jacobi smeared quark…
Excited hadrons on the lattice: Baryons
Tommy Burch, Christof Gattringer, Leonid Ya. Glozman +4
We present results for masses of excited baryons from a quenched calculation with Chirally Improved quarks at pion masses down to 350 MeV. Our analysis of the correlators is based…
Excited hadrons on the lattice: Mesons
Tommy Burch, Christof Gattringer, Leonid Ya. Glozman +3
We present results for masses of excited mesons from quenched calculations using chirally improved quarks at pion masses down to 350 MeV. The key features of our analysis are the u…
