Scientific paper

In a fourth generation model with heavy quarks, the production cross section
of the Higgs boson in the gluon-gluon fusion process is significantly increased
due to additional quark loops. In a similar way, the partial decay width of the
decay channels $H\rightarrow gg, \gamma \gamma$ and $\gamma Z$ is modified.
These changes and their impact on the Higgs search are discussed.
