Improved background modeling for dark matter search with COSINE-100

G. H. Yu, Nelson Carlin, Jin Yeon Cho, J. J. Choi et autres

Abstract COSINE-100 aims to conclusively test the claimed dark matter annual modulation signal detected by DAMA/LIBRA collaboration. DAMA/LIBRA has released updated analysis results by lowering the energy threshold to 0.75 keV through various upgrades. They have consistently claimed to have observed an …

Development of MMC-based lithium molybdate cryogenic calorimeters for AMoRE-II

Aman Agrawal, В. В. Аленков, Pabitra Aryal, H. Bae et autres

The AMoRE collaboration searches for neutrinoless double beta decay of $^{100}$Mo using molybdate scintillating crystals via low temperature thermal calorimetric detection. The early phases of the experiment, AMoRE-pilot and AMoRE-I, have demonstrated competitive discovery potential. Presently, the AMoRE-II experiment, featuring a large …

Projected background and sensitivity of AMoRE-II

Aman Agrawal, В. В. Аленков, Pabitra Aryal, Joern Beyer et autres

AMoRE-II aims to search for neutrinoless double beta decay with an array of 423 Li$_2$$^{100}$MoO$_4$ crystals operating in the cryogenic system as the main phase of the Advanced Molybdenum-based Rare process Experiment (AMoRE). AMoRE has been planned to operate in three phases: …

Radioassay of the materials for AMoRE-II experiment

Aman Agrawal, В. В. Аленков, Pabitra Aryal, H. Bae et autres

The AMoRE-II experiment will search for the 0νββ decay of 100Mo nuclei using molybdate crystal scintillators, operating at milli-Kelvin (mK) temperatures, with a total of 80 kg of 100Mo. The background goal for the experiment is 10–4 counts/keV/kg/year in the region of …

Search for inelastic WIMP-iodine scattering with COSINE-100

Govinda Adhikari, N. Carlin, J. J. Choi, Seonho Choi et autres

We report the results of a search for inelastic scattering of weakly interacting massive particles (WIMPs) off $^{127}$I nuclei using NaI(Tl) crystals with a data exposure of 97.7 kg$\cdot$years from the COSINE-100 experiment. The signature of inelastic WIMP-$^{127}$I scattering is a nuclear …

Alpha backgrounds in the AMoRE-Pilot experiment

В. В. Аленков, H. Bae, J. Beyer, R. S. Boiko et autres

Abstract The Advanced Mo-based Rare process Experiment (AMoRE)-Pilot experiment is an initial phase of the AMoRE search for neutrinoless double beta decay of $$^{100}$$ 100 Mo, with the purpose of investigating the level and sources of backgrounds. Searches for neutrinoless double beta …

Initial performance of the COSINE-100 experiment

Govinda Adhikari, P. Adhikari, E. Barbosa de Souza, Nelson Carlin et autres

COSINE is a dark matter search experiment based on an array of low background NaI(Tl) crystals located at the Yangyang underground laboratory. The assembly of COSINE-100 was completed in the summer of 2016 and the detector is currently collecting physics quality data …

Muon detector for the COSINE-100 experiment

H. Prihtiadi, Govinda Adhikari, P. Adhikari, Nelson Carlin et autres

The COSINE-100 dark matter search experiment has started taking physics data with the goal of performing an independent measurement of the annual modulation signal observed by DAMA/LIBRA. A muon detector was constructed by using plastic scintillator panels in the outermost layer of …
