A Coupling of Pseudo Nambu Goldstone Bosons to Other Scalars and Role in Double Field Inflation
arXiv:astro-ph/9405045 · doi:10.1103/PhysRevD.50.7731
Abstract
We find a coupling of Pseudo Nambu Goldstone bosons (PNGBs) to other (ordinary) scalars, and consider its importance in various contexts. Our original motivation was the model of Double Field inflation [1]. We also briefly consider the role of this coupling for the case of the QCD axion.
