Abstract
We derive bounds on Higgs and gauge–boson anomalous interactions using the CDF data for the process p p ̄ →γγγ+X . We use a linearly realized SU L (2)× U Y (1) invariant effective Lagrangian to describe the bosonic sector of the Standard Model, keeping the fermionic couplings unchanged. All dimension–six operators that lead to anomalous Higgs interactions involving γ and Z are considered. We also show the sensitivity that can be achieved for these couplings at Fermilab Tevatron upgrades.
