Espriu, D. (Domènec)Katanaeva, Alisa2021-05-042021-05-042020-04-142470-0010https://hdl.handle.net/2445/176981We put forward a new bottom-up AdS/QCD holographic model bearing a distinct treatment of the pion fields. We argue that a standard approach to the pion description is neither transparent nor totally satisfactory. In the paper we provide a new one based on a broadened realization of some holographic principles. The reasoning and the effect of these modifications are explained in detail. The resulting model has a different set of parameters than the standard AdS/QCD case. We use them to calculate an extensive list of QCD quantities and find a rather good agreement with the experimental data.18 p.application/pdfengcc by (c) American Physical Society, 2020http://creativecommons.org/licenses/by/3.0/es/Física de partículesSimetria trencada (Física)Mesons (Física nuclear)Particle physicsBroken symmetry (Physics)Mesons (Nuclear physics)info:eu-repo/semantics/article7104552021-05-04info:eu-repo/semantics/openAccess
