景观中的意外通货膨胀

Accidental Inflation in the Landscape

Jose J. Blanco-Pillado, Marta Gomez-Reino, Konstantinos Metallinos

摘要:

我们研究了弦论通量紧致化中暴胀情景的微调,特别是在偶然暴胀模型中。我们调查的可能性,明显的微调的低能量参数的理论需要有通货膨胀可以generally通过扫描的值的通量在景观。此外,我们发现,在这个模型中存在一个永恒的通货膨胀景观为我们提供了一个自然的理论,在我们的真空中的通货膨胀时期的初始条件。我们通过对约化模空间的通量真空的数值研究,证明了这两种效应是如何在与卡-丘流形P^4_[1,1,1,6,9]的复杂结构相关的景观的一个小角落中起作用的。这使我们能够直接从通量中获得这个微型景观中通货膨胀的可观测参数的分布。

英文摘要:

We study some aspects of fine tuning in inflationary scenarios within string theory flux compactifications and, in particular, in models of accidental inflation. We investigate the possibility that the apparent fine-tuning of the low energy parameters of the theory needed to have inflation can be generically obtained by scanning the values of the fluxes over the landscape. Furthermore, we find that the existence of a landscape of eternal inflation in this model provides us with a natural theory of initial conditions for the inflationary period in our vacuum. We demonstrate how these two effects work in a small corner of the landscape associated with the complex structure of the Calabi-Yau manifold P^4_[1,1,1,6,9] by numerically investigating the flux vacua of a reduced moduli space. This allows us to obtain the distribution of observable parameters for inflation in this mini-landscape directly from the fluxes.
