Nambu-Goldstone和自发洛伦兹破缺引力理论中的质量模
Nambu-Goldstone and Massive Modes in Gravitational Theories with Spontaneous Lorentz Breaking
摘要:
局部洛仑兹对称性的自发破缺是普朗克尺度下物理学的一种可能机制。然而,如果这种破缺发生了,它就提出了这样的问题:南部-戈德斯通模式的命运是什么,希格斯机制是否会发生,以及是否会出现额外的大质量模式(类似于希格斯粒子)。这里介绍了最近研究这些问题的一些工作的摘要。
英文摘要:
Spontaneous breaking of local Lorentz symmetry is of interest as a possible mechanism originating from physics at the Planck scale. If such breaking occurs, however, it raises the questions of what the fate of the Nambu-Goldstone modes is, whether a Higgs mechanism can occur, and whether additional massive modes (analogous to the Higgs particle) can appear. A summary of some recent work looking at these questions is presented here.
