Update on the recent progress of the CUORE experiment


Abstract in English

CUORE is a 741 kg array of 988 TeO$_2$ bolometeric crystals designed to search for the neutrinoless double beta decay of $^{130}$Te and other rare processes. CUORE has been taking data since summer 2017, and as of summer 2018 collected a total of 86.3 kg$cdot$yr of TeO$_2$ exposure. Based on this exposure, we were able to set a limit on the $0 ubetabeta$ half-life of $^{130}$Te of $T^{0 u}_{1/2}>1.5times10^{25}$ yr at 90% C.L. At this conference, we showed the decomposition of the CUORE background and were able to extract a $^{130}$Te $2 ubetabeta$ half-life of $T_{1/2}^{2 u}=[7.9pm0.1 mathrm{(stat.)}pm0.2 mathrm{(syst.)}]times10^{20}$ yr. This is the most precise measurement of this half-life and is consistent with previous measurements.
