The author evaluates t-quark production and decay mechanisms within the framework of the standard SU(3)/sub c/ x SU(2)/sub L/ x U(1)/sub Y/ model. The t signal at p anti p colliders is plagued by serious backgrounds, but systematic procedures involving transverse momentum cuts on decay products, and lepton isolation cuts, are proposed. Possible new fourth-generation quarks (a,v) are introduced, and detection possibilities are studied. Two cases of v-quark mass are particularly interesting: (1) overlapping generations (m/sub v/ < M/sub t/) in which the v quark may be unusually long-lived and (2) supermassive quarks (m/sub v/ > M/sub W/ + m/sub t/) which decay into real vector bosons. Electroweak W pair production and decay are evaluated as a benchmark to compare with fourth-generation quarks. Possibilities for detecting a new, fourth-generation heavy lepton L at p anti p colliders is investigated. Heavy leptons with m/sub L/ < 60 GeV should be detectable at the CERN collider.
