# Relativistic Correction to Color Octet J/psi Production at Hadron Colliders

@article{Xu2012RelativisticCT, title={Relativistic Correction to Color Octet J/psi Production at Hadron Colliders}, author={Guang-Zhi Xu and Yi-Jie Li and Kuiyong Liu and Yu-Jie Zhang}, journal={Physical Review D}, year={2012}, volume={86}, pages={094017} }

The relativistic corrections to the color-octet $J/\psi$ hadroproduction at the Tevatron and LHC are calculated up to $\mathcal{O}(v^2)$ in nonrelativistic QCD factorization frame. The short distance coefficients are obtained by matching full QCD with NRQCD results for the partonic subprocess $g+g\to J/\psi ({}^1S_0^{[8]},{}^3S_1^{[8]}, {}^3P_J^{[8]})+g$, $q+\bar{q}\to J/\psi ({}^1S_0^{[8]},{}^3S_1^{[8]}, {}^3P_J^{[8]})+g$ and $g+q({\bar{q}})\to J/\psi ({}^1S_0^{[8]},{}^3S_1^{[8]}, {}^3P_J^{[8…
