ar X iv : h ep - p h / 97 10 50 2 v 1 2 8 O ct 1 99 7 Hadron Spectroscopy from the Lattice

Lattice QCD determinations appropriate to hadron spectroscopy are reviewed with emphasis on the glueball and hybrid meson states in the quenched approximation. Hybrids are discussed for heavy and for light quarks. The effects of sea quarks (unquenching) are explored. Heavy-light systems are presented particularly excited B mesons.

We review the possibility to use the renormalons emerging in the perturbation series of the twist-2 part of the nonsinglet structure functions F L , F 2 , F 3 , and g 1 to make approximate predictions for the magnitude of the appertaining twist-4 corrections.
