We present a complete evaluation for $J/\ensuremath{\psi}({\ensuremath{\psi}}^{\ensuremath{'}})$ prompt production at the Tevatron and LHC at next-to-leading order in nonrelativistic QCD, including color-singlet, color-octet, and higher charmonia feeddown contributions. The short-distance coefficients of $^{3}P_{J}^{[8]}$ at next-to-leading order are found to be larger than leading order by more than an order of …
