Quenching Effects in the Hadron Spectrum
arXiv:hep-lat/0406025 · doi:10.1007/11356462_1
Abstract
Lattice QCD has generated a wealth of data in hadronic physics over the last two decades. Until relatively recently, most of this information has been within the "quenched approximation" where virtual quark--anti-quark pairs are neglected. This review presents a descriptive discussion of the effects of removing this approximation in the calculation of hadronic masses.
