The ANAIS-112 experiment, with a target of 112.5 kg of NaI(Tl), has been running smoothly at the Canfranc Underground Laboratory (Spain) since 2017. It aims to test this observation using the same detection technique and target. Results on the modulation search from two years of data (220.7 kg·y) have been presented and the analysis of three years (313.6 kg·y) is underway. Under the hypothesis of modulation, the deduced amplitudes from best fits are in all cases compatible with zero for the two energy regions at [2–6] and [1–6] keV; the results agree with the expected sensitivity for the considered exposure and fully support the goal of achieving a 3σ sensitivity to explore the DAMA/LIBRA result for a five-year operation. Here, the ANAIS-112 set-up and performance will be briefly recapped and the annual modulation results and prospects will be discussed. info:eu-repo/grantAgreement/ES/MICINN/FPI-CSD2009-00064 info:eu-repo/grantAgreement/ES/MICINN/PID2019-104374GB-I00 info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio/CSD2007-00042 info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2017-83133-P info:eu-repo/grantAgreement/ES/MINECO/FPA2017-90566-REDC info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Cebrián, Susana Universidad de Zaragoza (orcid)0000-0002-6948-5101 Cintas, David Universidad de Zaragoza (orcid)0000-0001-5187-2640 Coarasa, Iván Universidad de Zaragoza (orcid)0000-0002-8100-1368 García, Eduardo Universidad de Zaragoza (orcid)0000-0002-9827-2332 Martínez, María Universidad de Zaragoza (orcid)0000-0002-9043-4691 Oliván, Miguel (orcid)0000-0001-7025-061X Ortigoza, Ysrael Universidad de Zaragoza (orcid)0000-0002-2793-7544 Ortiz de Solórzano, Alfonso Universidad de Zaragoza (orcid)0000-0001-8278-6032 Puimedón, Jorge Universidad de Zaragoza (orcid)0000-0001-8732-8196 Salinas, Ana Universidad de Zaragoza (orcid)0000-0001-9508-8567 Sarsa, María Universidad de Zaragoza (orcid)0000-0002-7552-1228 Villar, Patricia Universidad de Zaragoza (orcid)0000-0002-6519-4315 2004 X Universidad de Zaragoza Dpto.
