As a step toward a fundamental understanding of hybrid states we demonstrate the close relationship between the relativistic
string and lattice simulation results for excited glue states with two fixed color sources.
Because of the self-interacting nature of the gluon it is
possible, even with fixed color (QQ) sources, to have an
infinite set of excited glue states. The known mesons and
baryons correspond to quark motion in the glue ground
state configuration. For excited glue a vastly richer
hadron spectrum of hybrid states then results, which can
have important experimental consequences.
Before serious models of hybrid spectroscopy are at-
tempted, it is important to investigate the central ques-
tion of possible glue states with fixed color charges. From
