Fragmentation contributions to hadroproduction of prompt $J/\psi$, $\chi_{cJ}$, and $\psi(2S)$ states
We compute leading-power fragmentation corrections to hadroproduction of charmonium states J/ψ, χcJ , and ψ(2S) in the nonrelativistic QCD factorization formalism. We include fragmentation functions through order α 2 s and parton production cross sections through order α 3 s . We also resum leading...
