论文摘要
在LHC，RHIC和TEVATRON ENERGIES上的$χ_{C} $和$χ_{B} $的中央独家生产，使用包装TMDLIB包中可用的最新未集成的Parton Distribution（UGDS）功能，分析了TMDLIB中的最新未集成的Parton Distribution（UGDS）功能。与数据进行了比较，该比较测试了基于理论方法的基本假设，并且可以约束在小$ x $区域的未集成的gluon分布函数。提供了使用基于CCFM形式主义的最近UGD的LHC能量的预测。它探讨了该产量上的基本不确定性，因为已经完成了未整合的Gluon分布和分解量表的选择。此外，基于Parton饱和模型的GLUON分布，提出了快速分布的分析表达式。 $ J/ψ+γ$和$υ+γ$的迅速产生是在用于$χ$生产的同一形式主义中首次计算的LHC Energies。
The central exclusive production of $χ_{c}$ and $χ_{b}$ at the LHC, RHIC and Tevatron energies is analyzed, using the recent unintegrated parton distribution (UGDs) functions available in the package TMDlib. Comparison with data is performed, which tests the underlying assumptions basing the theoretical approach and it can constrain the unintegrated gluon distribution function at the small-$x$ region. Predictions for LHC energies using recent UGDs based in CCFM formalism are provided. It is explored the underlying uncertainties on this production as the choice for the unintegrated gluon distribution and factorization scale is done. Moreover, based on the parton saturation model for the gluon distribution, analytical expressions for the rapidity distributions are proposed. The prompt production of $J/ψ+γ$ and $Υ+γ$ is computed for the first time for LHC energies within the very same formalism used for $χ$ production.
