Muon-induced neutrons can lead to potentially irreducible backgrounds in rare event search experiments. In this talk, we discuss recent progress on BSM and dark matter searches in CUORE. New searches for low mass dark matter, solar axions, CPT and Lorenz violations, and refined measurements of the 2νββ spectrum in CUORE have the potential to provide new insight and constraints on extensions to the standard model complementary to other particle physics searches. The large exposure, sharp energy resolution, segmented structure and radio-pure environment make CUORE an ideal instrument for a wide array of searches for rare events and symmetry violations. After beginning its first physics data run in 2017, CUORE has since collected the largest amount of data ever acquired with a solid state detector and provided the most sensitive measurement of 0νββ decay in 130Te ever conducted. The detector, located underground at the Laboratori Nazionali del Gran Sasso in Italy, consists of 988 TeO2 crystals arranged in a compact cylindrical structure of 19 towers, operating at a base temperature of about 10 mK. The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric 0νββ experiment to reach the one-tonne mass scale. We did not observe a ionization production threshold down to 100 eV. The measured ionization yield is consistent with previous measurements above 2 keV and presents a deviation to lower yield with respect to the Lindhard model. In this talk, we will present the first ionization yield measurement in silicon down to an energy of 100 eV.Ī silicon-based SuperCDMS HVeV cryogenic calorimetric detector was operated in a monochromatic neutron beam at the Triangle Universities Nuclear Laboratory (Durham, North Carolina) as part of the IMPACT program.Ī coincidence measurement between the silicon detector and a liquid scintillator backing array selects six fixed neutron energies (from 4 keV to 100 eV). Therefore, the precise knowledge of the nuclear recoil ionization yield is essential for nuclear recoil measurement. We will present details of the background model construction, discuss sources of systematic uncertainty, and report on the deployment of skipper CCDs in DAMIC at SNOLAB to perform a more precise spectral measurement by the end of 2022.ĭirect-detection experiments searching for dark matter-nucleon interactions with a charge-based readout are commonly calibrated using sources interacting with the electron of the detector target.īut nuclear and electron interactions produce a different amount of charge for the same energy deposition. We reported a conspicuous excess of events above our background model below 200 eV$_$, whose origin remains unknown. Results include exclusion limits on the existence of hidden-sector DM candidates and low-mass weakly interacting massive particles (WIMPs). From 2017 to 2019, DAMIC collected dark-matter search data with a seven-CCD array (40-gram target) installed in a low radiation environment in the SNOLAB underground laboratory. The low pixel noise provides DAMIC with sensitivity to ionization signals of only a few charges, for a remarkably low energy threshold. The DAMIC experiment employs large area, thick charge-coupled devices (CCDs) to search for the interactions of low-mass dark matter (DM) particles in the galactic halo with silicon atoms in the CCD target. The following topics are the focus of the conference: We also aim to give you a real experience of the city and of the surrounding by a Danube river cruise and local, traditional cuisine at the wine tavern Heuriger Fuhrgassl-Huber. We particularly want to encourage the active participation of young researchers in the field and we plan to publish peer-reviewed proceedings. We warmly invite you to come and present talks or posters and to join in lively discussions covering all aspects of the study of dark matter and of the hunt to identify its nature. The aim of IDM is to draw a complete picture of the current knowledge of dark matter from cosmological scale down to particle physics, from accelerator searches to recent results in indirect and direct detection and to give a glance at future prospects and technological advancements on the endeavor to identify dark matter. The conference will take place from 18-22th of July 2022 at the Technical University Vienna (TU Wien) which is located in the very center of the city in close walking distance to Vienna’s main attractions like Karlsplatz, Stephansdom, Naschmarkt etc. The 14th conference on the identification of dark matter - IDM2022 - is organized by the Institute of high energy physics (HEPHY) in the beautiful city Vienna. GROWING UP SKIPPER .GIF UPDATEAn update on COVID-related rules and measures will be published here in due time. IDM2022 is planned as an in-person conference in July 18-22, 2022.
