论文摘要
我们研究了两个HIGGS双重模型的新场景,其中可以同时解释Electroweak Rho参数的当前实验数据以及Higgs玻色子耦合的参数。在这种情况下,两个希格斯双重模型被认为是一个低能效率的理论,直至高能量尺度$λ$,高于该理论,高于该理论。假定希格斯的潜力尊重$λ$(扭曲的托管对称性)的全球对称性,这是由于$λ$上方基本理论的全球对称结构而给出的。通过使用单环重新归一化组方程的分析,即使额外的希格斯玻色子的质量接近电牵引量表,也可以自然地解释上述实验数据。我们还讨论了有关其他希格斯玻色子的质谱的预测,以及标准模型样希格斯玻色子的耦合常数的预测,这使得可以在当前和未来的碰撞器实验中测试这种情况。
We investigate a new scenario of the two Higgs doublet model, where the current experimental data for the electroweak rho parameter and those for the Higgs boson couplings can be simultaneously explained. In this scenario, the two Higgs doublet model is supposed to be a low energy effective theory up to a high energy scale $Λ$, above which a fundamental theory should appear. It is assumed that the Higgs potential respects a global symmetry at $Λ$ (the twisted custodial symmetry), which is to be given as a consequence of the global symmetry structure of the fundamental theory above $Λ$. By the analysis using one-loop renormalization group equations, the above experimental data can be explained in a natural way even when the masses of the extra Higgs bosons are near the electroweak scale. We also discuss the predictions on the mass spectrum of the additional Higgs bosons and also those on coupling constants of the standard-model-like Higgs boson, which make it possible to test this scenario at current and future collider experiments.
