论文摘要

标准模型有效场理论(SMEFT)是选择解释许多现代测量的参数化。我们最近在基于其他小组的工作的基础上讨论了其整体框架,可以实验测试,而不仅仅是限制其参数。这是因为Higgs有效的现场理论(HEFT)更为笼统,因为它并不认为Higgs Boson $ h $需要嵌入在复杂的Doublet $ h $中,该$ h $ h $ h $构建了标准模型(SM)和SMEFT。结果,各种相关通道的Heft参数空间包含超曲面,可以在其中使用SMEFT来描述数据。如果在任何各种通道中的任何一个中的任何一个在任何一个超曲面之外产生一个点的实验测量,则伪造了SMEFT;同时,其框架仍然适当(尤其是只要SM与数据兼容)。各种可能的测试的共同必要性是需要对比涉及不同数量的希格斯玻色子(保持其他颗粒的数量和性质)的过程。

The Standard Model Effective Field Theory (SMEFT) is the parametrization chosen to interpret many modern measurements. We have recently discussed, building on the work of other groups, that its overall framework can be experimentally tested, beyond simply constraining its parameters. This is because the Higgs Effective Field Theory (HEFT) is somewhat more general, as it does not assume that the Higgs boson $h$ needs to be embedded in a complex doublet $H$ on which the Standard Model (SM) and SMEFT are built. As a result, the HEFT parameter spaces for the various relevant channels contains hypersurfaces over which one may use SMEFT to describe data. If experimental measurements of HEFT's parameters in any of those various channels yield a point outside of any of the hypersurfaces, SMEFT is falsified; meanwhile, its framework remains appropriate (in particular, as long as the SM remains compatible with data). A common necessity of the various possible tests is that processes involving different number of Higgs bosons (maintaining the number and nature of other particles unchanged) need to be contrasted.
