使用单圈校正的希格斯玻色子玻色子耦合和未来精确测量对扩展希格斯扇区进行指纹识别

Fingerprinting the extended Higgs sector using one-loop corrected Higgs boson couplings and future precision measurements

Shinya Kanemura, Mariko Kikuchi, Kei Yagyu

摘要:

在软破缺离散$Z_2$对称下,计算了具有四种Yukawa相互作用的两个Higgs偶重态模型中单圈水平上125 GeV希格斯玻色子玻色子耦合常数的辐射修正.重正化计算在壳层方案中进行,其中的规范依赖的混合参数出现在前面的计算是一贯避免。我们首先详细介绍了重整化方案,并给出了重整化耦合的完整解析公式。然后,我们用数值方法演示了如何通过未来在高光度LHC和国际直线对撞机上对这些耦合的精确测量来提取模型的内部参数。

英文摘要:

We calculate radiative corrections to a full set of coupling constants for the 125 GeV Higgs boson at the one-loop level in two Higgs doublet models with four types of Yukawa interaction under the softly-broken discrete $Z_2$ symmetry. The renormalization calculations are performed in the on-shell scheme, in which the gauge dependence in the mixing parameter which appears in the previous calculation is consistently avoided. We first show the details of our renormalizaton scheme, and present the complete set of the analytic formulae of the renormalized couplings. We then numerically demonstrate how the inner parameters of the model can be extracted by the future precision measurements of these couplings at the high luminosity LHC and the International Linear Collider.
