在标准模型中运行通货膨胀

Running Inflation in the Standard Model

Andrea De Simone, Mark P. Hertzberg, Frank Wilczek

摘要:

一个与曲率有较大耦合的相互作用标量场可以支持一个独特的暴胀宇宙方案。这在以前已经讨论过标准模型希格斯场,处理经典或在领先的对数近似。在这里我们用重整化群方法研究量子理论。在这个模型中,有效普朗克质量和耦合的运行都很重要。宇宙学预言与现有的WMAP 5数据一致,0.967 < n_s < 0.98(对于N_e = 60)和可忽略的重力波。我们发现光谱指数和希格斯质量之间的关系是急剧变化的m_h ~ 120-135 GeV(取决于顶部的质量),在未来,这种关系可以测试对普朗克和LHC的数据。我们也简要地评论如何类似的动态可能会出现在更一般的设置,并讨论我们的假设从有效场论的观点。

英文摘要:

An interacting scalar field with largish coupling to curvature can support a distinctive inflationary universe scenario. Previously this has been discussed for the Standard Model Higgs field, treated classically or in a leading log approximation. Here we investigate the quantum theory using renormalization group methods. In this model the running of both the effective Planck mass and the couplings is important. The cosmological predictions are consistent with existing WMAP5 data, with 0.967 < n_s < 0.98 (for N_e = 60) and negligible gravity waves. We find a relationship between the spectral index and the Higgs mass that is sharply varying for m_h ~ 120-135 GeV (depending on the top mass); in the future, that relationship could be tested against data from PLANCK and LHC. We also comment briefly on how similar dynamics might arise in more general settings, and discuss our assumptions from the effective field theory point of view.
