We present the complete electroweak radiative corrections of O(\\alpha) to these processes, including improvements beyond O(\\alpha) originating from heavy-Higgs effects and final-state radiation. The intermediate W- and Z-boson resonances are described (without any expansion or on-shell approximation) by consistently employing complex mass parameters for the gauge bosons (complex-mass scheme). The corrections to partial decay widths typically amount to some per cent and increase with growing Higgs mass M_H, reaching about 8% at M_H \\sim 500 GeV. For not too large Higgs masses (M_H <\\sim 400 GeV) the corrections to the partial decay widths can be reproduced within <\\sim 2% by simple approximations. For angular distributions the corrections are somewhat larger and distort the shapes. For invariant-mass distributions of fermion pairs they can reach several tens of per cent depending on the treatment of photon radiation. The discussed corrections have been implemented in a Monte Carlo event generator called PROPHECY4F.","journal":"Physical Review D","year":2006,"id":10125,"datarank":0.8499640032168649,"base_score":5.666426688112432,"endowment":5.666426688112432,"self_citation_contribution":0.8499640032168649,"citation_network_contribution":0.0,"self_endowment_contribution":0.8499640032168649,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":288,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.0589,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2006-07-12","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":39956,"name":"Stefan Dittmaier","orcid":"0000-0003-2487-3650","position":2,"is_corresponding":false},{"id":85880,"name":"M.
