论文摘要
我们使用HIGGS有效的田间理论（HEFT）计算了Fermion-Loop校正为高能$ W^+W^ - $散射。我们测试了以下假设：与玻色环相比，这些校正可以忽略不计，因为在文献中通常认为这些校正是理所当然的。虽然这是正确的，但我们发现，对于参数空间的某些特定区域，费米亚环可能很重要：与其标准模型值的耦合耦合的偏差可能会导致Fermion-loop校正与Boson-loop相关。
We calculate fermion-loop corrections to high energy $W^+W^-$ scattering in the context of a Strongly Interacting Electroweak Symmetry Breaking Sector (EWSBS) using Higgs Effective Field Theory(HEFT). We test the assumption that these corrections are negligible when compared to the boson-loop ones, as it is commonly taken for granted in the literature. While this is correct inmost cases, we find that, for some particular regions of the parameter space, fermion-loops can be important: deviations in the couplings of the HEFT from their Standard Model values may lead to fermion-loop corrections as relevant as the boson-loop ones.
