Abstract
In this talk, we present the QCD factorization formula for heavy quarkonium production at large with factorized leading-power and next-to-leading power contributions in the expansion. We show that the leading order analytical calculations in this QCD factorization approach can reproduce effectively the full next-to-leading order numerical results derived using non-relativistic QCD (NRQCD) factorization formalism. We demonstrate that the next-to-leading power contributions are crucial to the description of the channels that are the most relevant for the rate as well as polarization of production at current collider energies.
