While the first model has a discrete spectrum of Kaluza-Klein (KK) modes, the second one has a continuous spectrum above a mass gap. We also study the positivity of the spectral functions, as well as the coupling of the graviton and the radion with SM matter fields}, organization = {Project PID2020- 114767GB-I00}, organization = {MCIN/AEI/10.13039/501100011033}, organization = {FEDER/Junta de Andalucía- Consejería de Economía y Conocimiento 2014-2020 Operational Program under Grant A-FQM-178- UGR18}, organization = {Junta de Andalucía under Grant FQM-225}, organization = {Ramón y Cajal Program of the Spanish MCIN under Grant RYC-2016-20678}, organization = {Spanish MCIN under Grant FPA2017-88915-P,}, organization = {Catalan Government under Grant 2017SGR1069}, organization = {MCIN under Grant SEV- 2016-0588}, organization = {IFAE}, organization = {CERCA program of the Generalitat de Catalunya}, publisher = {EPJ Web of Conferences}, title = {Physics of warped dimensions: discrete and continuous spectra}, doi = {10.1051/epjconf/202227408002}, author = {Megías Fernández, Eugenio and Quirós, Mariano}, }
