论文摘要
我们研究了颜色相关性对双方散射（DPS）的贡献。我们表明，当这些颜色相关的贡献并没有被横向尺度抑制Sudakov时，有一个与所谓的1 \ textrightArrow {} 2个过程相关的特定类别的Feynman图。分裂量表随横向刻度Q的增加而增加，颜色相关性高达5-10％。有效缺乏Sudakov抑制作用使人们希望，尽管它们相对于颜色的单线相关性很小，但最终可以观察到它们。
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.
