引力Higgs机制的非微扰么正性

Non-perturbative Unitarity of Gravitational Higgs Mechanism

Alberto Iglesias, Zurab Kakushadze

摘要:

本文利用引力Higgs机制讨论了闵可夫斯基空间中的大质量引力,给出了一个非微扰的定义。使用这种非微扰的定义,我们解决的问题,通过研究完整的非线性哈密顿量的相关度量自由度的么正性。虽然微扰么正性不明显,我们认为,没有负范数状态是目前在全非线性理论。

英文摘要:

In this paper we discuss massive gravity in Minkowski space via gravitational Higgs mechanism, which provides a non-perturbative definition thereof. Using this non-perturbative definition, we address the issue of unitarity by studying the full nonlinear Hamiltonian for the relevant metric degrees of freedom. While perturbatively unitarity is not evident, we argue that no negative norm state is present in the full nonlinear theory.
