Description

The EXO-200 Collaboration searched for neutrinoless double beta decay ($0\nu \beta \beta$) using a liquid xenon time projection chamber filled with ~150 kg of enriched ${}^{136}$Xe from September 2011 to December 2018. The use of a multi-dimensional analysis including calorimetric, spatial and topological information for the events allowed EXO-200 to perform one of the most sensitive searches for ($0\nu \beta \beta$) to date. For the final analysis, advanced techniques such as a Deep Neural Network were deployed to maximize the topological discrimination between signal and gamma backgrounds. This talk will present the analysis of the full dataset from EXO-200, including the final 0nbb result and other physics searches.
