Abstract
We investigate the spectroscopy of scalar and vector Kaluza–Klein modes that arise in a deformed Randall–Sundrum model that is constructed from Brans–Dicke theory. The non-minimal coupling in the Brans–Dicke theory translates into a deformation of the Randall–Sundrum geometry that depends on the Brans–Dicke parameter ω. We find that the ω parameter has a nontrivial effect in the spectroscopy of scalar and vector Kaluza–Klein modes. Our results suggest the interpretation of ω as a fine-tuning parameter.
