Scalar induced top decays may drastically suppress [ital B]([ital t][r arrow][ital l][nu]+jet) and still hide the top below [ital M][sub [ital W]]. The [ital p[bar p]] collider experiments should enlarge the scope and study the [ital m][sub [ital t]-][ital B]([ital t][r arrow][ital l][nu][ital j]) plane. Specific model signatures such as [ital t][r arrow][ital ch][sup 0][r arrow][ital cb[bar b]] (multiple high [ital p][sub [ital T]] [ital b] jets) and [ital t][r arrow][ital bH][sup +][r arrow][ital bc[bar s]], [ital b][tau][sup +][nu] [with [ital B]([ital t][r arrow][ital b][tau][nu])[approx lt]1/3] should be explored. Without ruling out these possibilities, isolated lepton signals in the future might actually be due to the fourth generation [ital t][prime] or [ital b][prime] quark, while top quark and toponium physics could still turn up at the CERN [ital e][sup +][ital e][sup [minus]] LEP-II collider.
