AbstraktAbstract
The SuperNEMO Experiment has entered its physics data-taking phase as of April 2025, becoming the only operational double beta decay detector capable of full topological event reconstruction via the tracker-calorimeter design. This topology-driven approach provides powerful discrimination of signal and background, and is uniquely suited to explore a wide range of BSM scenarios. The detector, located at the Laboratoire Souterrain de Modane (LSM) in France, uses 6.11 kg of enriched 82Se as its double beta decay source. We present the first simulation-based sensitivity estimates using the newly developed tracking algorithm and an updated analysis framework, targeting both the 0νββ mode and other exotic decays such as Majoron-emitting decays and the right-handed currents. The extended analysis takes advantage of SuperNEMO’s capability to measure not only the total electron energy but also single-electron energies and angular correlations. These results represent an important step toward quantifying SuperNEMO’s sensitivity to a broad range of double beta decay processes.
