Understand

Progress in computing the spectrum of excited baryons and mesons in lattice QCD is described.

Large sets of spatially-extended hadron operators are used.
The need for multi-hadron operators in addition to single-hadron operators is emphasized, necessitating the use of a new stochastic method of treating the low-lying modes of quark propagation which exploits Laplacian Heaviside quark-field smearing.
A new glueball operator is tested and computing the mixing of this glueball operator with a quark-antiquark operator and multiple two-pion operators is shown to be feasible.
