标题： Perturbative Color Correlations in Double Parton Scattering

摘要： 我们研究颜色相关性对双部分子散射(DPS)的贡献。 我们表明，当这些颜色相关性的贡献没有被横截面尺度的Sudakov抑制时，存在一类与所谓1\textrightarrow{}2过程相关的费曼图。 分裂尺度随着横截面尺度Q的增加而增加，颜色相关性可达单态相关性的5-10%。 Sudakov抑制的有效缺失使得人们希望，尽管它们相对于颜色单态相关性来说很小，但最终可以被观测到。 显示英文摘要

摘要： We study the contribution of color correlations to Double Parton Scattering (DPS). We show that there is a specific class of Feynman diagrams related to so called 1 \textrightarrow{} 2 processes when the contribution of these color correlations is not Sudakov suppressed with the transverse scales. The split scale increases with the transverse scale Q, with color correlations being up to 5-10 percent of singlet ones. The effective absence of Sudakov suppression gives hope that although they are small relative to color singlet correlations, they eventually can be observed.
