AI 中文总结
本文对面向LHC的HiggsTools框架的三个子包进行改进，新增能量截面预测、多顶末态搜索复现等功能，使其适配LHC Run 3及HL-LHC研究需求。
AI 中文摘要
HiggsTools是一个超出标准模型（BSM）标量现象学的工具箱，包含HiggsPredictions、HiggsBounds和HiggsSignals三个子包，用于大型强子对撞机（LHC）相关研究。该工具可提供BSM模型预测，将模型与BSM标量搜索的实验限制进行比对，并从已发现希格斯玻色子的性质测量中推导约束。本文对HiggsTools框架进行了多项改进，使其适配LHC Run 3及高亮度LHC（HL-LHC）的结果。HiggsPredictions新增了质心能量为13.6和14 TeV的额外截面预测，还包含了共振与非共振希格斯玻色子对产生的截面预测；HiggsBounds方面，描述了多顶末态搜索的复现方法、其实现方式及实验灵敏度的影响，讨论了非共振希格斯玻色子对产生的耦合依赖限制，以及希格斯玻色子发现前开展的搜索处理方式的改进；HiggsSignals则描述了针对带质量不确定的标量的多项改进。
英文摘要
HiggsTools, including the subpackages HiggsPredictions, HiggsBounds, and HiggsSignals, is a toolbox for Beyond-the-SM (BSM) scalar phenomenology at the LHC. It provides BSM model predictions, tests the model against experimental limits from searches for BSM scalars and derives constraints from the measurements of the properties of the discovered Higgs boson. We present a variety of improvements to the HiggsTools framework, preparing it for the results of LHC Run 3 and the HL-LHC. HiggsPredictions now provides additional cross-section predictions for centre-of-mass energies of 13.6 and 14 TeV. Moreover, it now includes cross-section predictions for resonant and non-resonant Higgs-boson pair production. For HiggsBounds, we describe the recasting of searches using multi-top final states, explain their implementation and highlight the impact of the experimental sensitivity of those results. Furthermore, we discuss the implementation of coupling-dependent limits on non-resonant Higgs boson pair production, as well as the improved handling of searches conducted prior to the Higgs boson discovery. For HiggsSignals we describe several improvements for the case of scalars with mass uncertainties.
