We discuss the form and construction of general color singlet heavyparticle-antiparticle pair production currents for arbitrary quantum numbers,and issues related to evanescent spin operators and scheme-dependences innonrelativistic QCD (NRQCD) in n=3-2epsilon dimensions. The anomalousdimensions of the leading interpolating currents for heavy quark and coloredscalar pairs in arbitrary (2S+1)L_J angular-spin states are determined atnext-to-leading order in the nonrelativistic power counting.Comment: 39 pages, 2 tables, 10 figures; typos corrected, published versio
