论文摘要
我们讨论了两个Higgs Doublet模型的参数空间通过考虑LHC处的其他Higgs玻色子的协同作用以及其光度升级的操作和精确测量，并在未来的Electron-Positron colliders等国际固定器（例如International Linefore collider）等高度升级了Higgs玻色子，从而显着缩小了范围。我们表明，在发现的希格斯玻色子的耦合常数与标准模型中的预测值略有不同的地方，大多数参数空间都通过直接搜索额外的希格斯玻色子的直接搜索，尤其是在发现的希格斯玻色子中的额外的higgs boson和contrime interiality anderiality ander的范围中，例如，均等均匀地进行了provum ander ander ander的宣传。这可以做到，因为只要Higgs玻色子耦合中存在偏差，额外的希格斯玻色子的质量就会上限。我们还表明，在对齐限制中，所有希格斯玻色子耦合都采用标准模型，就像大多数参数空间一样，因为大多数希格斯对higgs衰减的衰减都被抑制了，并且从理论参数中质量也没有上限。
We discuss a possibility that the parameter space of the two Higgs doublet model is significantly narrowed down by considering the synergy between direct searches for additional Higgs bosons at the LHC and its luminosity upgraded operation and precision measurements of the Higgs boson properties at future electron-positron colliders such as the International Linear Collider. We show that, in the case where the coupling constants of the discovered Higgs boson are slightly different from the predicted values in the standard model, most of the parameter space is explored by the direct searches of extra Higgs bosons, in particular for the decays of the extra Higgs bosons into the discovered Higgs boson, and also by the theoretical arguments such as perturbative unitarity and vacuum stability. This can be done because there appears an upper limit on the mass of the extra Higgs bosons as long as the deviation exists in the Higgs boson coupling. We also show that in the alignment limit where all the Higgs boson couplings take the standard model like values most of the parameter space cannot be excluded because most of the Higgs to Higgs decays are suppressed and also there is no upper limit on the masses from the theoretical arguments.
