动力学对称破缺与宇宙学常数问题

Dynamical symmetry breaking and the cosmological constant problem

Philip D. Mannheim

摘要:

我们概述了一个计划,有可能解决宇宙学常数和量子引力问题在一个单一的,全面的框架,一个是制定完全在四个时空维度。该计划是基于粒子物理学的动力学对称破缺和引力理论,共形引力,它具有一个潜在的局部共形不变结构之间的相互作用。讨论的核心是认识到,当对称性动态破缺的共形不变理论,宇宙学常数都诱导和约束的零点波动。我们描述了仍然需要做的事情。

英文摘要:

We outline a program with the potential to solve both the cosmological constant and quantum gravity problems within a single, comprehensive framework, one that is formulated entirely in four spacetime dimensions. The program is based on an interplay between the dynamical symmetry breaking of particle physics and a gravity theory, conformal gravity, which possesses an underlying local conformal invariant structure. Central to the discussion is the recognition that when symmetry is broken dynamically in a conformal invariant theory, the cosmological constant is both induced by and constrained by zero-point fluctuations. We describe what still needs to be done.
