Their mass pattern and decay modes exhibit certain distinguishing features and characteristic signals. For example, when the CERN LHC and, possibly a future version of the SSC are built, pair production of the vectorlike quarks would lead to systems such as ([ital b[bar b]]+4[ital Z]+[ital W][sup +][ital W][sup [minus]]) and ([ital b[bar b]]+2[ital Z]+[ital W][sup +][ital W][sup [minus]]), while an [ital e][sup [minus]][ital e][sup +] linear collider (NLC) of suitable energy can produce appreciably a single neutral heavy lepton [ital N] together with [nu][sub [tau]], followed by the decay of [ital N] into ([ital Z]+[nu][sub [tau]])[r arrow]([ital e][sup [minus]][ital e][sup +])+[nu][sub [tau]]. This last signal may conceivably materialize even at CERN LEP 200 if [ital N] is lighter than about 190 GeV.
