Scientific paper

We have examined decays of low-lying gluonic excitations of mesons (hybrids) by chromoelectric flux-tube breaking. An analytical calculation of non-relativistic flux-tube model decay amplitudes is performed in an harmonic oscillator approximation. Specific decay signatures of all $J^{PC}$ charmonium hybrids are identified and the widths predicted. We introduce a new selection rule which can be used to understand the systematics of numerical decay calculations.
