论文摘要
我们对panscales parton阵雨的次近级对数（NLL）精确度进行了广泛的测试，这是最近在强子碰撞中介绍的颜色单林生产的。这些测试包括与（半）分析NLL计算的比较，对广泛的强体挑可观测值：颜色 - 单孔玻色子横向动量分布；全球和非全球辐射能量流量变量与喷气源和害虫分布的类似物有关； （sub）喷气倍数；并观察到对传入动量分数的DGLAP演变敏感。在测试中，我们还包括实现标准的横向摩托式偶极淋浴的实现，以确定此类阵雨中缺少NLL效果的大小，根据可观察到的可观察到的，可以达到$ 100 \％$ $。本文与Arxiv：2205.02237一起构成了朝着无关的NLL准确的Parton淋浴进行HADRONIC碰撞的第一步。
We carry out extensive tests of the next-to-leading logarithmic (NLL) accuracy of the PanScales parton showers, as introduced recently for colour-singlet production in hadron collisions. The tests include comparisons to (semi-)analytic NLL calculations of a wide range of hadron-collider observables: the colour-singlet boson transverse momentum distribution; global and non-global hadronic energy flow variables related to jet vetoes and analogues of jettiness distributions; (sub)jet multiplicities; and observables sensitive to the DGLAP evolution of the incoming momentum fractions. In the tests, we also include an implementation of a standard transverse-momentum ordered dipole shower, to establish the size of missing NLL effects in such showers, which, depending on the observable, can reach $100\%$. This paper, together with arXiv:2205.02237, constitutes the first step towards process-independent NLL-accurate parton showers for hadronic collisions.
