Experimental evidence for various sources of prompt leptons produced in hadronic collisions is discussed. Emphasis is placed on sources of prompt single leptons and prompt multileptons. Such final states are expected from production and subsequent weak decays of short lived states. Hadronic charm production cross sections of 20 μb per nucleon at 400 GeV account for the observed single lepton signal as well as dileptons with missing energy (indicative of final state neutrinos). Limits of 40 μb/nucleon for bottom particle production in 400 GeV proton collisions are extracted from multimuon final state signatures. Various prompt dilepton sources (such as Drell‐Yan and resonance production) are also summarized.
