Search for the Θ(1540) in lattice QCD
We report on a study of the pentaquark Θ(1540), using a variety of different interpolating fields. We use Chirally Improved fermions in combination with Jacobi smeared quark sources to improve the signal and get reliable results even for small quark masses. The results of our quenched calculations, which have been done on a 12 × 24 lattice with a lattice spacing of a = 0.148 fm, do not provide ...
