We find it is a natural result for any theory where at least one flavor of fermion acquires its mass through a Yukawa coupling to a scalar field which has nonvanishing vacuum expectation value.","journal":"Physical Review Letters","year":1977,"id":2745,"datarank":21.31224023646617,"base_score":8.849657406639912,"endowment":8.849657406639912,"self_citation_contribution":1.3274486109959869,"citation_network_contribution":19.984791625470184,"self_endowment_contribution":1.3274486109959869,"citer_contribution":19.984791625470184,"corpus_percentile":93.8,"corpus_rank":1823,"citation_count":6971,"citer_count":198,"citers_with_citation_signal":198,"citers_with_endowment":198,"datacite_reuse_total":0,"is_dataset":false,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"1977-06-20","authors":[{"id":15318,"name":"Helen R.
