Applications of Double Beta Decay
Abstract- Double beta decay, a rare nuclear process in which two neutrons within a nucleus are simultaneously transformed into two protons with the emission of two electrons, has garnered significant attention for its profound implications in particle physics, cosmology, and beyond. This paper explores the diverse applications of double beta decay, emphasizing both two-neutrino and neutrinoless modes. The importance of accurate theoretical calculations of nuclear matrix elements is discussed, addressing methods the shell model and QRPA. These calculations are crucial for interpreting experimental results and reducing uncertainties. Additionally, potential connections with dark matter interactions and the cosmic neutrino background are explored. The interdisciplinary applications of double beta decay research, including advancements in nuclear medicine, environmental monitoring, and geophysics, are also examined, showcasing the broader impact of this field. This paper synthesizes current knowledge and experimental findings, outlines ongoing and future research directions, and discusses the potential technological and theoretical breakthroughs that could arise from continued investigation into double beta decay. By providing a comprehensive overview, this work aims to underline the significance of double beta decay in modern physics and its wide ranging applications.
