关于引力子的Higgs机制

Remarks on Higgs Mechanism for Gravitons

Ichiro Oda

摘要:

我们构造了两种表现引力子在标量场势场中的Higgs机制的模型。一类模型是基于一个势,它是诱导的内部度量$H^{AB}$的类属函数;另一类模型是基于一个势,它是通常度量张量$g_{μν}$和诱导的弯曲度量$Y_{μν}$的类属函数。在这两个模型中,我们都导出了在没有非幺正传播模的平坦Minkowski时空中,引力子通过标量场的凝聚,在对称性破缺自发对称性破缺过程中获得质量的标量势条件.我们解决的条件,并找到一个普遍的解决方案的潜力。作为一个有趣的特解,我们提出了一个简单的势,在任何宇宙学常数值下,引力子的希格斯机制都成立。

英文摘要:

We construct two kinds of model exhibiting Higgs mechanism for gravitons in potentials of scalar fields. One class of the model is based on a potential which is a generic function of the induced internal metric $H^{AB}$, and the other involves a potential which is a generic function of the usual metric tensor $g_{μν}$ and the induced curved metric $Y_{μν}$. In the both models, we derive conditions on the scalar potential in such a way that gravitons acquire mass in a flat Minkowski space-time without non-unitary propagating modes in the process of spontaneous symmetry breaking of diffeomorphisms through the condensation of scalar fields. We solve the conditions and find a general solution for the potential. As an interesting specific solution, we present a simple potential for which the Higgs mechanism for gravitons holds in any value of cosmological constant.
