论文摘要
包括$ j/ψ$，$ψ（2s）$和$υ（1s）$ Direct和解决的光增生性，可以通过在非相关性量子染色体动力学（NRQCD）的框架中包括Quark子过程来研究。我们发现，一旦考虑到了$γq$，$ qg $和$ qq $ subprocesses，重型夸克$，在重型夸克对中的$γq$，$ QQ $，$γq$，$ quark $ subprocesses一旦考虑到了重型夸克对的理论总横截面。 $ j/ψ$，$ψ（2s）$和$υ（1s）$，$ pp $，$ ppb $和$ PBPB $ collisions在LHC中还研究了包含衍射的速度和横向动量分布，我们的Quark Reved Reved NRQCD模型还研究了LHC的$ PBPB $ Collisions。我们发现，Quark涉及子过程的贡献可以达到速度分布的$ 8 \％$，而横向动量分布的$ 6 \％$。数值结果表明，Quark涉及子过程的贡献在重夸克光生剂中很重要。
The inclusive $J/Ψ$, $Ψ(2S)$ and $Υ(1S)$ direct and resolved photoproduction are investigated by including the quark subprocesses in the framework of non-relativistic quantum chromodynamics (NRQCD). We find that the theoretical total cross section of heavy quarkonium productions are in good agreement with the data available at HERA, once the $γq$, $qg$ and $qq$ subprocesses in the heavy quark pair productions are taken into account. The inclusive diffractive rapidity and transverse momentum distributions of $J/Ψ$, $Ψ(2S)$ and $Υ(1S)$ in $pp$, $pPb$ and $PbPb$ collisions at LHC are also studied by our quark improved NRQCD model combined with the resolved pomeron model. We find that the contributions from the quark involved subprocesses can reach to $8\%$ in the rapidity distribution and $6\%$ in the transverse momentum distribution. The numerical results show that the contributions from quark involved subprocesses are significant in heavy quarkonium photoprodution.
