摘要

我们提出了一种场的重新定义，它简化了电弱对称破缺部门的希格斯有效场理论拉格朗日。这种简化产生了相同的壳上散射振幅，同时大大减少了$\omega\omega\to n\times h$过程的费曼图数量（在TeV尺度上，费曼图通过等效定理近似于$W_LW_L\to n\times h$振幅）。

Redefining Higgs interactions at the TeV scale

We present a field redefinition that simplifies the Higgs Effective Field Theory Lagrangian for the Electroweak Symmetry Breaking Sector. This simplification produces the same on-shell scattering amplitudes while greatly reducing the number of contributing Feynman diagrams for $\omega\omega\to n\times h$ processes (which approximate the $W_LW_L\to n\times h$ amplitudes at the TeV scale by means of the Equivalence Theorem).
