运行质量暴胀模型与原初黑洞

Running-Mass Inflation Model and Primordial Black Holes

Manuel Drees, Encieh Erfani

摘要:

我们重新审视运行质量暴胀模型是否允许形成原始黑洞(PBH),这些黑洞的寿命足够长,可以作为暗物质的候选者。我们将最近的宇宙学数据,包括WMAP 7年的结果。此外,我们还包括了功率谱的谱指数的“运行的运行”,以及暴胀子质量项的“运行的运行”的重整化群。我们的分析表明,在这种情况下,仍然有可能形成足够重的,因此寿命长的PBH。作为一个副产品,我们表明,在暴胀子潜在的附加项仍然不允许显着的负运行的谱指数。

英文摘要:

We revisit the question whether the running-mass inflation model allows the formation of Primordial Black Holes (PBHs) that are sufficiently long-lived to serve as candidates for Dark Matter. We incorporate recent cosmological data, including the WMAP 7-year results. Moreover, we include "the running of the running" of the spectral index of the power spectrum, as well as the renormalization group "running of the running" of the inflaton mass term. Our analysis indicates that formation of sufficiently heavy, and hence long-lived, PBHs still remains possible in this scenario. As a by-product, we show that the additional term in the inflaton potential still does not allow significant negative running of the spectral index.
