我们考虑在模拟中改进P owheg+ M，以使它们在描述从较低部分多重性的事件中获得的贡献的观测值时，也比在其基础NLO计算中存在的NLO准确。在概念层面上，我们遵循所谓的M - inlo计划的策略。鉴于现有的inlo框架需要来自高阶恢复的明确的分析输入，在这里，我们通过施加统一性推导出这些成分的有效数值近似。这提供了一种将M inlo方法扩展到更复杂过程的方法，补充了使用高精度恢复输入的显式计算的已知路径。具体来说，我们专注于希格斯加双射流生产（hjj）和相关工艺。我们还考虑如何在NLO精度下覆盖三个多重单位，即我们考虑hjj - m inlo模拟如何产生包含H， H j和H jj数量的NLO精度。我们进行可行性研究，评估这些想法的潜力。
We consider improving P owheg+ M inlo simulations, so as to also render them NLO accurate in the description of observables receiving contributions from events with lower parton multiplicity than present in their underlying NLO calculation. On a conceptual level we follow the strategy of the so-called M inlo′ programs. Whereas the existing M inlo′ framework requires explicit analytic input from higher order resummation, here we derive an effective numerical approximation to these ingredients, by imposing unitarity. This offers a way of extending the M inlo′ method to more complex processes, complementary to the known route which uses explicit computations of high-accuracy resummation inputs. Specifically, we have focused on Higgs-plus-two-jet production (H jj) and related processes. We also consider how one can cover three units of multiplicity at NLO accuracy, ie we consider how the H jj-M inlo simulation may yield NLO accuracy for inclusive H, H j and H jj quantities. We perform a feasibility study assessing the potential of these ideas.
