Neutrino-less double beta decay experiments are critical for determining whether neutrinos are Majorana fermions. Current predictions suggest that if neutrinos exhibit an inverted hierarchy, definitive results may be available within 5 to 10 years. However, if neutrinos follow a normal hierarchy, these experiments may yield inconclusive results, making the timeline for clarity uncertain. The sensitivity of these experiments is essential for gathering sufficient data to answer this fundamental question in particle physics.
