 +   <hidden TTP00-04  Light Hybrid Mesons in QCD > Including the radiative perturbative corrections and the short 
 + distance tachyonic gluon mass effects which mimic the ones of UV 
 + renormalons, we re-estimate the decay amplitudes, masses and widths of 
 + light hybrid mesons from QCD spectral sum rules. We show that the 
 + effects are tiny and confirm the previous lowest order results. We 
 + discuss the phenomenological impacts of our results for the vector 
 + hybrids.
