Abstract

Abstract: For J/Ψ+1jet inclusive production at the LHC, within the non-relativistic QCD (NRQCD) framework, in this work a full next-to-leading order (NLO) calculation with the anti-kt algorithm for the jet is presented. The J/Ψ is considered to be not contained in the jet. The predictions are made for the total cross section, J/Ψ transverse momentum distribution, jet transverse momentum distribution and the J/Ψ jet rapidity difference distribution for this process. It is found that the process is detectable in the experiment, and the color-octet long distance matrix elements(LDMEs) fitted in the J/Ψ inclusive production by different groups are not consistent in the J/Ψ+1jet inclusive production process, which makes a reexamination for the fit of the J/Ψ LDMEs necessary.

Key words: jet, Large Hardron Collider, non-relativistic QCD, long distance matrix elements
