LHC上J/Ψ伴随一个喷注的单举产生过程
J/Ψ+1jet inclusive production process at the LHC
摘要
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.关键词
