Description
We present the first complete study of $\Upsilon$ and prompt $J/\psi$ production from single-parton scattering to the complete O($\alpha_s^6$) for color singlet contribution and including all leading SPS contributions. We find that the effective cross section characterizing the importance of double-parton scatterings is $\sigma_{eff}$≤8.2 mb at 68% confidence level from the D0 measurement. At the same time, we also present $J/\psi+J/\psi$ production at hadron colliders.
