关于大质量自旋2的电磁相互作用

On massive spin 2 electromagnetic interactions

Yu. M. Zinoviev

摘要:

本文利用规范不变量描述研究了(A)dS空间中自旋为2的大质量粒子在线性近似下的电磁相互作用。我们遵循自下而上的方法,即我们从引入最小相互作用开始,然后通过添加具有越来越多导数的非最小相互作用以及相应的非最小修正来进行规范变换,直到我们能够恢复被过渡破坏的规范不变性到规范协变导数。我们设法构造了一个模型,该模型在(A)dS空间中的无质量粒子和平坦Minkowski空间中的有质量粒子之间平滑地插值。此外,我们再现了相同的结果,在框架式的形式主义,可以更适合于更高的自旋的推广。

英文摘要:

In this paper we investigate electromagnetic interactions for massive spin 2 particles in (A)dS space at linear approximation using gauge invariant description for such massive particles. We follow bottom-up approach, i.e. we begin with the introduction of minimal interaction and then proceed by adding non-minimal interactions with higher and higher number of derivatives together with corresponding non-minimal corrections to gauge transformations until we are able to restore gauge invariance broken by transition to gauge covariant derivatives. We manage to construct a model that smoothly interpolates between massless particle in (A)dS space and massive one in a flat Minkowski space. Also we reproduce the same results in a frame-like formalism which can be more suitable for generalizations on higher spins.
