ANAIS-112 results will be presented this week @MoriondEW21 and Rutgers University – HEX Seminars

Three years ANAIS-112 results on annual modulation will be presented this week:

-at the conference 55th Rencontres de Moriond 2021, EW session. This year in a different format: Moriond@home, but interesting as always.

-at Rutgers University High Energy Experimental Seminars

New ANAIS-112 results on annual modulation – three years exposure

ANAIS-112 experiment is taking data at Canfranc Underground Laboratory since August 2017 in order to test DAMA/LIBRA signal. Updated results for three years and 112.5 kg, together with complementary analysis and consistency checks have been posted in arXiv this week:

We confirm our sensitivity estimates and tension with DAMA/LIBRA results (for 2.7 / 2.5 sigma sensitivities in the two energy regions considered).

Enhorabuena a Clara Cuesta, premio L’Oreal-Unesco 2021

Clara Cuesta, investigadora aragonesa y que formó parte durante varios años del equipo investigador del experimento ANAIS, ha sido galardonada con uno de los cinco premios L’Oréal-Unesco “For Women in Science” en su edición de 2021.

Clara, que ahora trabaja en el CIEMAT, estudia las propiedades de los neutrinos, elusivas partículas que sin embargo se espera que en el próximo futuro nos ayuden a entender mucho mejor el Universo y, por el camino, a desarrollar nuevas tecnologías.

¡Enhorabuena Clara! Un merecido reconocimiento.

Científicas en el Altoaragón

Este próximo 11F se celebra en Huesca “virtualmente” esta esupenda jornada.

El experimento ANAIS y la búsqueda de materia oscura en el Laboratorio Subterráneo de Canfranc forman parte del programa. ¡Muy interesante! No os lo perdáis.

Online Seminar on ANAIS-112 status and results by María Martínez @ CIEMAT

El próximo 29 de octubre de 2020 a las 11:30h María Martínez Pérez presentará los resultados más recientes de ANAIS-112 en el CIEMAT en formato de seminario “online”.

Dark Matter annual modulation and ANAIS-112 results: testing the DAMA/LIBRA positive signal


The evidence for dark matter (DM) is overwhelming from astrophysical and cosmological observations at all scales. Yet, its existence is inferred indirectly through gravitational effects, but its nature is still unknown. Among the preferred DM particle candidates are Weakly Interacting Massive Particles (WIMPs), new particles beyond the standard model (SM) with weak-scale couplings to SM particles. WIMPs in the Milky Way halo are expected to scatter off the nuclei of a particle detector located in the Earth, with an interaction rate that depends on their relative velocity with respect to the Earth. As a consequence of the Earth rotation around the Sun, this velocity varies with 1 year periodicity, and so does the expected interaction rate (annual modulation). For more than 20 years, the DAMA/LIBRA experiment at the Gran Sasso Underground Laboratory (Italy) has claimed a positive dark matter detection: an annual modulation in the low-energy detection rate compatible with the expected signal induced by dark matter particles. This signal is in strong tension with the negative results of other very sensitive experiments. However, until recently a direct comparison using the same target material (NaI(Tl)) was lacking.

ANAIS (annual modulation with NaI Scintillators) is a dark matter direct detection experiment located at the Canfranc Underground Laboratory (LSC, Spain). Its main goal is to test in a model independent way the DAMA/LIBRA positive result. ANAIS-112, consisting of 112.5 kg of NaI(Tl) scintillators, was installed at the LSC in 2017 and since then is taking data smoothly with excellent performances. Last year we released results from the first two years of data, which are compatible with the absence of modulation and in some tension with DAMA/LIBRA result. Moreover, the results support our goal of reaching a 3sigma sensitivity to the DAMA/LIBRA result with about 5 years of data-taking.

In this seminar I will briefly review the DAMA/LIBRA puzzle and the status of the experiments trying to reproduce it. Then I will introduce the ANAIS-112 experimental set-up, the detector performance and analysis methods. Finally, I will present the latest results and an update of the experimental sensitivity.

First announcement of TAUP2021 (Valencia, 30 Aug – 3 Sep 2021)

We are glad to announce that the 17th International Conference on Topics in Astroparticle and Underground Physics (TAUP 2021) is scheduled to take place in Valencia, Spain.

TAUP 2021

Dates: 30 August – 3 September 2021
Venue: Valencia Conference Center, Spain
Preliminary website:

The biennial TAUP series covers recent experimental and theoretical developments in astroparticle physics by invited plenary review talks and parallel workshop sessions of invited and contributed presentations.

Topics covered by the conference include:

  * Cosmology and particle physics
  * Dark matter and its detection
  * Neutrino physics and astrophysics
  * Gravitational waves
  * High-energy astrophysics and cosmic rays

The website of the TAUP Conference series is:

While the Local Organizing Committee is already working towards an in-person TAUP conference, other options could be considered depending on the evolution of the COVID-19 worldwide crisis.
