The Hadron Spectrum from Lattice QCD
arXiv:0711.3091 · doi:10.1016/j.ppnp.2007.12.026
Abstract
Determining the hadron spectrum and hadron properties beyond the ground states is a challenge in lattice QCD. Most of these results have been in the quenched approximation but now we are entering the dynamical era. I review some of the ideas and methods of the lattice approach, concentrating on a few examples and on results obtained for Chirally Improved (CI) fermions.
