Abstract:

We derive the width of the Higgs boson into vector bosons. General formulas are derived both for the on-shell decay H -> VV as well for the off-shell decays, H -> V^* V and H -> V^* V^*, where V=\gamma,W,Z. For the off-shell decays the width of the decaying vector boson is properly included. The formulas are valid both for the Standard Model as well as for arbitrary extensions. As an example we study in detail the gauge-invariant effective Lagrangian models where we can have sizable enhancements over the Standard Model that could be observed at LEP.

Higgs particle: hadronic decay
gauge boson: pair production
gauge boson: off-shell
Higgs particle: width
Higgs particle: branching ratio
Higgs particle: mass
gauge boson: width
vertex function: (Higgs particle 2gauge boson)
effective Lagrangian
electroweak interaction: model
