Exotic decays refers to theoretical models or experimental observations of particle decays that do not fit within the standard model of particle physics. These decays might involve new and unknown particles, interactions, or decay modes that have not been previously observed. Research in exotic decays aims to better understand the fundamental properties of particles and their interactions, as well as to search for signs of new physics beyond the standard model. The study of exotic decays is a key area of research in high-energy physics and particle collider experiments.
