Abstract
- We present the first complete study of Υ and prompt J/ψ production from single-parton scattering, including the complete O(αS6) color-singlet contribution, the O(αS²α²) electroweak contribution, and the complete nonrelativistic S-wave and P-wave color-octet contribution as well as the feeddown contribution. Our study was motivated by the recent evidence reported by the D0 Collaboration of prompt J/ψ and Υ simultaneous production at the Tevatron. With our complete evaluation, we are able to refine the determination of the double-parton scattering contribution made by the D0 Collaboration. We find that the effective cross section characterizing the importance of double-parton scatterings is σeff≤8.2 mb at 68% confidence level from the D0 measurement. [ABSTRACT FROM AUTHOR]
