The Exotic Baryon Theta^+(1540) on the Lattice
Dieter Hierl, Christian Hagen, Andreas Schaefer
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 meson spectroscopy with chirally improved fermions
T. Burch, C. Gattringer, L. Glozman +4
We present excited meson masses from quenched calculations using chirally improved (CI) quarks at pion masses down to 350 MeV. The salient features of our analysis are the use of a…
Baryon spectroscopy with spatially improved quark sources
Tommy Burch, Christof Gattringer, Leonid Ya. Glozman +4
We study baryons on the lattice with a special focus on excited states. For that purpose we construct several interpolators which differ in their Dirac structure. These interpolato…
Pion scattering on the lattice with chirally improved fermions
Christof Gattringer, Dieter Hierl, Rainer Pullirsch
We report preliminary results for the I=2 pion scattering length a_0, calculated with chirally improved fermions. After chiral extrapolation our results are in good agreement with…
