我们研究了在希格斯-膨胀膨胀模型的有效场论描述中散射振幅（超越）正性的后果。通过要求EFT与酉，因果，局部和Lorentz不变UV完成兼容，我们推导出对第一高阶导数算子的Wilson系数的约束。我们表明，所允许的值的限制是一致的希格斯-膨胀模型的唯象应用。
We study the consequences of (beyond) positivity of scattering amplitudes in the effective field theory description of the Higgs-Dilaton inflationary model. By requiring the EFT to be compatible with a unitary, causal, local and Lorentz invariant UV completion, we derive constraints on the Wilson coefficients of the first higher order derivative operators. We show that the values allowed by the constraints are consistent with the phenomenological applications of the Higgs-Dilaton model.
