Dilepton final states refer to a specific signature in high-energy particle collisions where two leptons (such as electrons or muons) are produced as the final particles. Studying dilepton final states can provide valuable information about the underlying physics processes that occur in these collisions, such as the production and decay of heavy particles like the Z boson or top quark. Dilepton final states are often used in experimental particle physics research to test the predictions of theoretical models and to search for new particles or phenomena beyond the Standard Model of particle physics. They are also an important tool for studying properties of the strong and weak nuclear forces.
