In October 2017 CUORE reported its first results in the search for neutrinoless double beta (0νββ) decay. In just a few months of operation CUORE accumulated 86.3 kg⋅yr of exposure in TeO2 corresponding to 24.0 kg⋅yr in 130Te. Alone CUORE set the most stringent limit on this half-life at T1∕2 > 1.3 × 1025 yr (90% C.L.). When combined with previous results from Cuoricino and CUORE-0, the half-life result is T1∕2 > 1.5 × 1025 yr (90% C.L.). The background index in the region of interest for the decay was observed to be 0.014 ± 0.002 counts/(keV⋅kg⋅yr), near the design goal of CUORE. Shown here is the best fit model from an unbinned extended maximum likelihood (UEML) fit of the data (solid blue line). This is overlaid on the spectrum of the 0νββ decay candidate events in the region of interest with gaussian error bars. The pink band is centered at the energy we would expect to see the decay with a width reflecting the systematic uncertainty in our energy reconstruction. The dashed blue line indicates a model with no 0νββ decay component. The peak at 2506 keV is attributed to 60Co decay. At the top are the normalized residuals of the model compared to the binned data points.
