can anyone tell me where to find a good reference that talks about $$e^+ e^-\rightarrow H \rightarrow f\bar{f}$$ where this describes an electron-positron annihilation into a Higgs that in term produces heavy leptons.

Any reference that explains this process thoroughly will do it. I have searched many books on weak interactions but none of which handled it except one book "Gauge theories of the Strong, Weak, and Electromangnetic Interactions" that only gave a fast glimpse about it but I couldn't understand it from there.

    $\begingroup$ because, a scalar (spin 0 like the Higgs boson) doesn't carry any spin. The propagator does not depend on the Minkowski indices (no $g^{\mu\nu}$, no $\gamma^\mu$ and stuff like this). $\endgroup$ – Paganini Mar 10 '15 at 20:38
