论文摘要
与理论约束相一致的双方分布的模型对于对双方散射的可靠描述至关重要。我们展示了如何逐步改进党之间的小横向距离极限的ANSATZ，例如，以10％的范围符合双Parton分布的总和规则。
Models for double parton distributions that are realistic and consistent with theoretical constraints are crucial for a reliable description of double parton scattering. We show how an ansatz that has the correct behaviour in the limit of small transverse distance between the partons can be improved step by step, such as to fulfil the sum rules for double parton distributions with an accuracy around 10%.
