摘要：
The complete matrix elements for e(+)e(-) --> b (b) over bar W+/-H-/+ and e(+)e(-) --> b (b) over bar H+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 (t) over bar pair production followed by the top decays into b (b) over bar W+/-H-/+ and b (b) over bar H+H- final states; (ii) H+H- signals in which H+/- --> hW(+/-) --> b (b) over bar W+/- and H+/- --> tb --> b (b) over bar W+/-. Top and Higgs finite width effects are included as well as all those due to the irreducible backgrounds.
