Homework Statement
I have to show that the couplings to the Higgs ( W+ W- h , ZZh, hhh, and e+e-h) are proportional to the mass squared (for bosons) or mass (for fermions) of the particles. But according to this problem I don't have to explicitly construct the interaction terms in the lagrangian.
Homework Equations
According to Peskin & Schroeder, page 716 we can construct the interaction terms and explicitly read off the couplings but that's not the method I'm looking for. I am supposed to only show that they have to be proportional to mass or mass squared depending on the statistics of the particles involved
The Attempt at a Solution
I tried to use the mass dimensions of the wave functions involved using the lagrangian dimension = 4 but that didn't help to relate it to the couplings. It might be necessary to use the properties of the higgs (symmetry breaking mass) but I don't know how to do it
