Lepton jets are a type of high-energy particle jets that are primarily composed of leptons, such as electrons and muons. These jets are produced in high-energy particle collisions, such as those in particle accelerators or from cosmic ray interactions, and play a crucial role in the study of fundamental particles and their interactions. Lepton jets are of particular interest in particle physics research because they can provide insights into the properties of heavy particles, such as the Higgs boson, as well as help uncover new physics beyond the Standard Model. Studying lepton jets can also help scientists better understand the dynamics of particle collisions and the behavior of fundamental forces.
