Web10. The electron-positron pair can produce directly a Higgs boson, but this process is very suppressed, because the coupling between the leptons and the Higgs is proportional to the tiny mass m e: g H e e = − i m e v, where v ≈ 246 G e V. On the other hand, the process e + e − → H Z is more likely to happen, because the coupling between ...
