J/ψ+1jet inclusive production process at the LHC

doi:10.7523/j.ucas.2024.048

Abstract

Abstract: For J/ψ+1jet inclusive production at the large hadron collider, within the non-relativistic quantum chromodynamics framework, in this work a full next-to-leading order 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 hadron collider (LHC), non-relativistic quantum chromodynamics (NRQCD), long distance matrix elements (LDMEs)
