Abstract.

The complete matrix elements for \(e^+e^-\rightarrow b\bar bW^\pm H^\mp\) and \(e^+e^-\rightarrow b\bar bH^+H^-\) are 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 analyse: (i) \(t\bar t\) pair production followed by the top decays into \(b\bar bW^\pm H^\mp\) and \(b\bar b H^+H^-\) final states; (ii) \(H^+H^-\) signals in which \(H^\pm\to h W^{\pm} \to b\bar b W^{\pm}\) and \(H^\pm\to tb\to b\bar b W^\pm\). Top and Higgs finite width effects are included as well as all those due to the irreducible backgrounds.
