Description
Spontaneously broken conformal sectors are ubiquitous in model-building. Despite this, little is understood about the Lagrangian for the dilaton, the Goldstone boson of broken scale invariance. We investigate the higher-derivative terms in the dilaton action, focusing on the unique four-derivative term allowed by symmetry. This term is closely related to the famous a-theorem, and we argue it can actually be calculated in a holographic realization of spontaneously broken scale invariance. We also discuss implications for model building and dilaton phenomenology.
