Abstract

The complete matrix element for $e^+e^-\rightarrow b\bar b W^+W^-$ is computed at tree-level within the Minimal Supersymmetric Standard Model. Rates of interest to phenomenological analyses at the Next Linear Collider are given. In particular, we study: - $t\bar t$ production and decay $t\bar t\ar (bW^+)(\bar bW^-)$ ; - $ZH$ production followed by $Z\ar b\bar b$ and $H\ar W^+W^-$ ; - $AH$ production followed by $A\ar b\bar b$ and $H\ar W^+W^-$ ; - $hW^+W^-$ production followed by $h\ar b\bar b$ . Top and Higgs finite width effects are included, as well as all those of the irreducible backgrounds.
