No significant excess of events over the Standard Model prediction is found. A simultaneous fit to the four decay modes yields upper limits on the production cross-section of a heavy Higgs boson times the branching ratio to Z boson pairs. 95% confidence level upper limits range from 0.53 pb at mH=195 GeV to 0.008 pb at mH=950GeV for the gluon-fusion production mode and from 0.31pb at mH=195GeV to 0.009pb at mH=950GeV for the vector-boson-fusion production mode. The results are also interpreted in the context of Type-I and Type-II two-Higgs-doublet models.",
