We discuss the form and construction of general color singlet heavy particle-antiparticle pair production currents for arbitrary quantum numbers, and issues related to evanescent spin operators and scheme-dependences in nonrelativistic QCD (NRQCD) in n=3-2epsilon dimensions. The anomalous dimensions of the leading interpolating currents for heavy quark and colored scalar pairs in arbitrary (2S+1)L_J angular-spin states are determined at next-to-leading order in the nonrelativistic power counting.

Semi-analytical NNLO QCD corrections to e+e- -> J/psi + chi_cJ are computed via asymptotic expansions, yielding large corrections that reduce scale dependence for some channels and a discrepancy with Belle data on the...
