景观的亚稳域

Metastable Domains of the Landscape

Michael Dine, Guido Festuccia, Alexander Morisse, Korneel van den Broek

摘要:

我们认为,绝大多数小宇宙学常数的通量真空是不稳定的,会迅速衰变成大的坍缩。超对称态是指具有大紧化体积的超对称态和近似超对称态。无论是弱弦耦合、扭曲还是非常轻的粒子的存在,它们本身都不足以使态成为合理的亚稳态。我们还推测了可能是宇宙吸引子的状态。

英文摘要:

We argue that the vast majority of flux vacua with small cosmological constant are unstable to rapid decay to a big crunch. Exceptions are states with large compactification volume and supersymmetric and approximately supersymmetric states. Neither weak string coupling, warping, or the existence of very light particles are, by themselves, enough to render states reasonably metastable. We speculate, as well, about states which might be cosmological attractors.
