SUMMARY
The branching ratio of Z bosons into lepton-antilepton pairs is equal for all leptons due to the universal coupling of the Z boson to leptons. The mass of the Z boson, being significantly greater than that of any lepton, minimizes phase space effects, resulting in a consistent branching ratio across different lepton types. This fundamental property of the Z boson ensures that its decay behavior remains uniform regardless of the lepton mass variations.
