摘要：
The additional weak corrections are calculated at the one-loop level to the process H0 --> Z0Z0 in the two-Higgs-doublet extension of the standard model. The corrections from the extra Higgs sector depends strongly on the masses of the Higgs sector and the ratio of the vacuum expectation values, tan beta. It shows that the general two-Higgs-doublet model admits flexibility in adjusting the one-loop corrections for the decay. When M(H0) < 1 TeV and with a relative light H1 mass and heavy H2, phi masses which we used in this paper, the additional corrections could approach a 15% reduction.
