This Demonstration describes the variation of the Higgs boson branching ratios
, for eight different decay modes, as a function of the Higgs boson mass
. The results are obtained using first-order perturbation theory. Curves are shown for Higgs decay into pairs of gauge bosons (γ, g, Z, and W) and some fermion/anti-fermion pairs (τ, c, b, t), for different values of the coupling constants
. This is, in fact, a simple simulation of what the world might look like if
. The effects of the coupling strengths on particle masses are not considered. You can display any one or combination of decay modes by marking the corresponding checkboxes.
