Update on the recent progress of the CUORE experiment
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 $$0\nu\beta\beta$$ half-life of $$^{130}$$Te of $$T^{0\nu}_{1/2}>1.5\times10^{25}$$ yr at 90% C.L. At this conference, we showed the decomposition of the CUORE background and were able to extract a $$^{130}$$Te $$2\nu\beta\beta$$ half-life of $$T_{1/2}^{2\nu}=[7.9\pm0.1 \mathrm{(stat.)}\pm0.2 \mathrm{(syst.)}]\times10^{20}$$ yr. This is the most precise measurement of this half-life and is consistent with previous measurements.
