The cosmological constant problem: a user's guide
摘要:
我们讨论了广义相对论在低能下的有效性,并将理论崩溃的阈值与观测到的宇宙学常数值联系起来。这表明存在${\cal O}(10^{-3}) eV$的质量标度,并且在大约$10^{-14}$水平上假定违反等效性原则。
英文摘要:
We discuss the validity of general relativity at low-energy and relate the threshold below which the theory breaks down with the observed value of the cosmological constant. This suggests the existence of a mass scale of ${\cal O}(10^{-3}) eV$ and a putative violation of the equivalence principle at about $10^{-14}$ level.
