Abstract
We present the results of a first exploration of meson spin interactions in the flux-tube model of Isgur and Paton. The model supports the view that long-range spin effects other than kinematical (Thomas) are small. Nonadiabatic effects somewhat enhance the long-range Thomas interaction in quark model mesons, and yield estimates for the spin splittings of the lowest hybrid mesons. We comment on the implications of these spin corrections for previous calculations of exotic hybrid decays.
