Interconnection phenomena in $W^{+}{W}^{-}$ and $t\bar{t}$ events

Abstract

I will attempt to survey some selected physics issues on QCD interconnection phenomena in the processes $e^{+}{e}^{-}\to W^{+}{W}^{-}\to$ 4 jets and $e^{+}{e}^{-}\to t\bar{t}\to b{W}^{+}\bar{b}{W}^{-}$. Possible consequences for LEP2 and future linear $e^{+}{e}^{-}$ colliders are briefly discussed.
