Dynamical Chirally Improved Quarks: First Results for Hadron Masses

Understand

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 Ginsparg-Wilson condition in good approximation.
• The pion mass we use is still large O(470 MeV) for the 16**3*32 lattices with lattice spacing of 0.15 fm.
• The hadron masses are obtained with the variational technique and the results compared with earlier quenched calculations with similar lattice parameters.
