论文摘要

在这项工作中,我们解决了三个问题:我们可以成功地描述(观察到的)与SMEFT语言中标准模型的偏差吗?我们可以使用SMEFT语言学习一些有关基础模型的基础模型的知识吗?如果未观察到偏差,如何进行?鉴于无数可行的BSM选项具有扩展标量扇区,我们建议将SMEFT广泛使用不仅是全球拟合工具(可能会错过与扩展标量扇区的偏差),还可以作为簿记框架,在该框架框架中,将SMEFT与SMEFT的结果拟合到单个观测值的结果,并以一致的方式提供,并以一致的方式进行了存档。然后可以根据具有扩展标量扇区的BSM模型来评估此类结果的兼容性。

In this work we address three questions: can we successfully describe (observed) deviations from the standard model in the SMEFT language? Can we learn something about the underlying, beyond the standard model, physics using the SMEFT language? If no deviation is observed, how to proceed? Given the myriad of viable BSM options with extended scalar sectors, we suggest a widespread use of SMEFT not just as a global fitting tool (that could miss out on deviations from extended scalar sectors) but also as a bookkeeping framework in which the results from SMEFT fits to individual observables are provided, reported, and archived in a consistent way. The compatibility of such individual results can then be assessed in the light of BSM models with extended scalar sectors.
