Universidad de Zaragoza (orcid)0000-0002-7158-9794 Background model of the ANAIS-112 dark matter experiment 2022 Access copy available to the general public Unrestricted The ANAIS (Annual modulation with NaI(Tl) Scintillators) experiment aims at the confirmation or refutation of the DAMA/LIBRA positive annual modulation signal in the low energy detection rate. ANAIS-112, consisting of nine 12.5 kg NaI(Tl) modules, is taking data since August, 2017 at the Canfranc Underground Laboratory (LSC) in Spain. Results from the analysis of three years of data are compatible with the absence of modulation. The background model developed for all nine ANAIS-112 detectors was established from commissioning data and non-blinded events in the first year of data taking. Now, background characterization is being improved profiting from the larger accumulated exposure available. Here, the background model is described and comparisons of model and measurements for energy spectra and counting rate time evolution for three-year exposure (considering different analysis conditions) are presented. info:eu-repo/grantAgreement/ES/DGA/E27-20R info:eu-repo/grantAgreement/ES/MICINN/PID2019-104374GB-I00 info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio2010-CPAN-CSD2007-00042 info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio2010-MULTI-DARK-CSD2009-00064 info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2017-83133-P info:eu-repo/grantAgreement/ES/MINECO/Spanish Red Consolider MultiDark FPA2017-90566-REDC info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 0.183 2022 Physics and Astronomy (miscellaneous) 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Cebrián, S.
