Conformal coupling of the scalar field with gravity in higher dimensions and invariant powers of the Laplacian

Abstract

The hierarchy of conformally coupled scalars with the increasing scaling dimensions ${\Delta }_k=k-d/2$, $k=1,2,3,...$ connected with the $k$-th Euler density in the corresponding space-time dimensions $d\ge 2k$ is proposed. The corresponding conformal invariant Lagrangian with the $k$-th power of Laplacian for the already known cases $k=1,2$ is reviewed, and the subsequent case of $k=3$ is completely constructed and analyzed.
