Abstract

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 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(3) x 24 lattice with a lattice spacing of a = 0.148fm, do not ...
