Abstract
The production, decay, and detection of a fourth-generation charged heavy lepton L at multi-TeV hadron supercolliders is discussed for masses m/sub L/>M/sub W/ and m/sub ..nu..//sub >//sub L/approx. =0. The leptonic and hadronic decay signals for single L production and LL-bar pair production are evaluated. In all channels examined the heavy-lepton signal is smaller than backgrounds from single and pair production of W/sup +- / and Z bosons. However, it may still be possible to detect a heavy lepton from its contribution to pX/sub T/+2 or 4 jets events where the Z(..--> nu..nu-bar)+jets background may be determined from measurements of (Z..-->..ll-bar)+jets events.
