论文摘要
我们表明，对于$ d $ dimensions，在$ d $ dimensions中，又称自发折断的韦尔（或形式）对称性的作用，也可以从$ d $ dimensions中获得。该结构在任何偶数方面都提供了Dilaton有效作用的明确形式。
We show that the Wess-Zumino action for the spontaneously broken Weyl (or conformal) symmetry, a.k.a dilaton effective action, in even $D$ dimensions can be obtained from the Kaluza-Klein dimensional reduction of the Lovelock action in $D+ε$ dimensions by taking the $ε\to 0$ limit, where the dilaton is identified with the metric in the extra dimension. The construction gives an explicit form of the dilaton effective action in any even dimensions.
