论文摘要
下一代电子峰值山利组的设计用于对标准模型及其扩展的精确研究，尤其是在希格斯行业中。我们考虑通过光子碰撞发现HIGGS配对生产中复合HIGGS模型的潜力。此过程是循环生成的，因此它提供了对所有希格斯耦合的访问，并且可以在相对较低的撞机能量以极化和非极化横截面中显示新的物理效应。因此，它与计划或制备的所有电子峰船对围栏相关。与标准模型预测的较大偏差存在于一般的复合希格斯模型中，作为一个或多个希格斯玻色子的耦合，或费米子和标量共振，修改了标准模型中存在的破坏性干扰。特别是，很大的效果是由于希格斯与顶部的新四分之一耦合以及浅标量共振的存在所致。
The next generation electron-positron colliders are designed for precision studies of the Standard Model and its extensions, in particular in the Higgs sector. We consider the potential for discovery of composite Higgs models in Higgs pair production through photon collisions. This process is loop-generated, thus it provides access to all Higgs couplings and can show new physics effects in polarized and unpolarized cross-sections starting at relatively low collider energies. It is, therefore, relevant for all electron-positron colliders planned or in preparation. Sizeable deviations from the Standard Model predictions are present in a general class of composite Higgs models, as couplings of one or more Higgs bosons to fermions, or fermionic and scalar resonances, modify the destructive interference present in the Standard Model. In particular, large effects are due to the new quartic coupling of the Higgs to tops and to the presence of a light scalar resonance.
