Book excerpt: This frankly speculative paper discusses ways in which leptons heavier than the tau (if they exist) might be found. The status of the tau is briefly reviewed, and methods for searching for sequential charged leptons beyond the tau and other charged leptons at PEP, PETRA, and CESR are sketched. Charged leptons with mass greater than 20 GeV/c2 might be found at proton accelerators in hadron-hadron, photon-hadron, or .nu.-hadron collisions. Unstable, neutral heavy leptons might have unique, conserved lepton number or nonunique lepton number. The most difficult leptons to detect are stable neutral heavy leptons; nevertheless, a possible detection method is suggested. The obvious solution to seeking the postulated leptons is an e/sup +/e− colliding beam storage ring with c.m. energy = several hundred GeV. Until such a machine is built, one can employ Z° .-->. L/sup +/ + L−; the use of R/sub Z°/ and GAMMA/sub Z°/ in this connection is discussed. If heavier Z°'s exist, the heavy lepton search can be extended to higher energies. Another solution for producing these leptons involves the use of clashing e/sup +/e− linear accelerators. Characteristics of storage rings are compared with those of clashing linacs; a general description is given of the proposed SLAC Linac-Collider, along with the physics that could be done at such a machine. 6 figures.
