====== TTP01-27 Next-to-leading-log renormalization-group running in heavy-quarkonium creation and annihilation ======
 
 
   <hidden TTP01-27  Next-to-leading-log renormalization-group running in heavy-quarkonium creation and annihilation > In the framework of potential NRQCD, we obtain the next-to-leading-log
 renormalization-group running of the matching coefficients for the heavy
 quarkonium production currents near threshold. This allows to obtain
 S-wave heavy-quarkonium production/annihilation observables with
 next-to-leading-log accuracy within perturbative QCD. In particular, we
 give expressions for the decays of heavy quarkonium to e^+e^- and to
 two photons.
