We explore the thermodynamics of AdS(5) black holes in two models: i) an improved holographic QCD model with a simple dilaton potential, and ii) the Stuckelberg model in 5D. In the former case, by applying techniques of singular perturbation theory, we obtain a resummation of the naive expansion at high temperatures, providing a good fit to the lattice data for the trace anomaly. In the latter, we find a solution of the equations of motion by considering an expansion in the conformal dimension of the current associated to the gauge field. 2020-10-21T10:44:49Z 2020-10-21T10:44:49Z 2019 info:eu-repo/semantics/conferenceObject Megías, E.
