Gamma-tracking and sensitivity to gamma-emitting backgrounds in SuperNEMO

International audienceSuperNEMO, successor to the NEMO3 experiment [1], is looking for the neutrinoless double beta decay. Its unique design [2], combining both tracking and calorimetry techniques, provides essential topological informations. Indeed, fully reconstructing the event kinematics : allows a powerful background discrimination, would discriminate between the several hypothesized underlying mechanisms, but also gives access to a variety of event topologies which can be used to measure the different background contributions. The SuperNEMO software relies on a range of algorithms to ensure a faithful event reconstruction. The improved detector performance for γ detection coupled to new γ-reconstruction algorithms, based on geometrical and Time-of-Flight criteria, will not only improve the measurements of the γ-emitter backgrounds (208Tl, 214Bi...) but also increase the sensitivity for the search of β β-decays to the excited states
