宇宙学常数作为层次的表现

Cosmological Constant as a Manifestation of the Hierarchy

Pisin Chen, Je-An Gu

摘要:

有人认为暗能量所暗示的宇宙学常数与普朗克尺度$M_{\rm Pl}$和标准模型尺度$M_{\rm SM}$之间众所周知的等级有关。在这里,我们进一步提出,解决这个层次问题的同一框架也必须解决宇宙学常数的小问题。具体来说,我们调查的最小超对称(SUSY)的Randall-Sundrum模型的超对称性断裂的TeV膜上诱导和传输到散装的扩展。我们证明了该系统的Casimir能量密度确实与观测到的暗能量尺度一致。

英文摘要:

There has been the suggestion that the cosmological constant as implied by the dark energy is related to the well-known hierarchy between the Planck scale, $M_{\rm Pl}$, and the Standard Model scale, $M_{\rm SM}$. Here we further propose that the same framework that addresses this hierarchy problem must also address the smallness problem of the cosmological constant. Specifically, we investigate the minimal supersymmetric (SUSY) extension of the Randall-Sundrum model where SUSY-breaking is induced on the TeV brane and transmitted into the bulk. We show that the Casimir energy density of the system indeed conforms with the observed dark energy scale.
