We examine the phenomenological implications at colliders for the existenceof higher-derivative gravity terms as extensions to the Randall-Sundrum model.Such terms are expected to arise on rather general grounds, e.g., from stringtheory. In 5-d, if we demand that the theory be unitary and ghost free, thesenew contributions to the bulk action are uniquely of the Gauss-Bonnet form. Wedemonstrate that the usual expectations for the production cross section anddetailed properties of graviton Kaluza-Klein resonances and TeV-scale blackholes can be substantially altered by existence of these additionalcontributions. It is shown that measurements at future colliders will be highlysensitive to the presence of such terms.Comment: 29 pages, 8 figure
