Query: Neutrinoless Double Beta Decay in the SNO+ Experiment   SNO+ is a large multipurpose neutrino detector situated 2km underground at
SNOLAB in Sudbury, Canada. It reuses the structure of the SNO experiment with
numerous infrastructure upgrades and with heavy water replaced by ultra-pure
liquid scintillator. The detector will be loaded with 0.5% natural tellurium in
order to search for neutrinoless double beta decay ($0\nu\beta\beta$). The
expected sensitivity after 5 years of data taking is T$^{0\nu} _{1/2} > 1.9
\times 10^{26}$ years (90% CL). A future increase in loading could achieve a
sensitivity of ${\sim}10^{27}$ years.
