We discuss the origin of the non-decoupling effects of the heavy Higgs bosons within the two Higgs doublet extension (THDM) of the standard model (SM) and illustrate it by means of the one-loop calculation of the differential cross sections of the process in both the decoupling and the non-decoupling regimes. We argue that there are many regions in the THDM parametric space in which the THDM and SM predictions differ by several percents and such effects could, at least in principle, be testable at the future experimental facilities.
