We review some recent developments in top quark production and decay at current and future colliders.

We investigate the charged Higgs boson contribution into $t\bar b$-pair production in pp-collisions at LHC. It is shown that due to the $\cz$-boson exchange the total yield of $t\bar b$ is modified significantly for small and large values…
