It is possible to extend the formalism for high- heavy quarkonium factorization beyond leading power. This extension may be helpful in interpreting the relative roles of octet and singlet channels in the formalism of nonrelativistic QCD (NRQCD). It may enable us to understand the origin of the surprisingly large results for cross sections calculated in the color singlet sector of NRQCD. [Copyright &y& Elsevier]
