Hybrids: Dynamics and Disguises

Abstract

We introduce general selection rules arizing from flux-tube dynamics with non-relativistic and adiabatic quark motion, without employing model-dependent assumptions. Specifically, we indicate under which circumstances hybrids with an arbitrary degree of flux-tube excitation can disguise themselves by not decaying to S--wave states.
