Abstract

Quantum entanglement has long served as a foundational pillar in understanding quantum mechanics, with a predominant focus on two-particle systems. We extend the study of entanglement into the realm of three-body decays, offering a more intricate understanding of quantum correlations. We introduce a novel approach for three-particle systems by utilising the principles of entanglement monotone concurrence and the monogamy property. Our findings highlight the potential of studying deviations from the Standard Model and emphasise its significance in particle phenomenology. This work paves the way for new insights into particle physics through multi-particle quantum entanglement, particularly in decays of heavy fermions and hadrons.
