论文摘要
为了使弦理论与对积极宇宙常数的低能观测兼容,已经尝试在弦理论中构建DS真空,这尤其难以实现。我们指出了一种使弦理论与低能DS宇宙学一致的新方法,而不是试图找到保姆(DS)真空解决方案。通过这种方式,弦理论生活在仅存在于高能制度中的反de保姆(AD)真空中(易于构造)。但是,随着进入低能量表,在其中集成了重弦激励和kaluza-klein模式,我们表明,较低维度中的弦理论的有效图片将显示出4D DS真空,而无需添加其他结构,例如抗D3麸皮。此外,我们指出了自下而上物理学的证据,证明了弦理论中从ADS真空实现的ADS距离猜想的强大版本。因此,该证据支持ADS距离猜想作为量子重力的普遍特征之一。
In order for string theory to be made compatible with the low-energy observations of a positive cosmological constant, there have been attempts to construct dS vacua in string theory which are particularly difficult to realize. Instead of attempting to find de Sitter (dS) vacuum solutions, we point to a new way to make string theory consistent with low-energy dS cosmology. In this way, string theory lives in an anti-de Sitter (AdS) vacuum (which is simple to construct) that exists only in the high-energy regime; however, as going to the low-energy scales where the heavy string excitations and Kaluza-Klein modes are integrated out, we show that the effective picture of string theory in lower dimensions would exhibit a 4D dS vacuum without needing to add additional structures such as anti-D3 branes. Additionally, we point to evidence from bottom-up physics for the strong version of the AdS distance conjecture realized from AdS vacua in string theory. This evidence hence supports the sharpening of the AdS distance conjecture as one of the universal features of quantum gravity.
