Abstract
We examine the colour structure and charged particle yield for both the\(t\bar t\) signal and the irreducible background processes contributing to\(e^ + e^ - \to b\bar bW^ + W^ - \) production close to the\(t\bar t\) threshold. The charged particle multiplicity for the various components of the cross section is computed as a function of several kinematic variables. Our study may have important implications for recently proposed studies of interconnection phenomena in\(t\bar t\) production at high-energye + e − colliders.
