We define this general framework by constructing a low-energy effective theory containing the Standard Model fields, with one or two Higgs doublets and, as the only source of SU(3)^5 flavour symmetry breaking, the background values of fields transforming under the flavour group as the ordinary Yukawa couplings. We analyse present bounds on the effective scale of dimension-six operators, which range between 1 and 10 TeV, with the most stringent constraints imposed by B -> X_s gamma. In this class of theories, it is possible to relate predictions for FCNC processes in B physics to those in K physics. We compare the sensitivity of various experimental searches in probing the hypothesis of MFV. Within the two-Higgs-doublet scenario, we develop a general procedure to obtain all tan(beta)-enhanced Higgs-mediated FCNC amplitudes, discussing in particular their impact in B -> l^+l^-, Delta M_B and B -> X_s gamma. As a byproduct, we derive some two-loop tan(beta)-enhanced supersymmetric contributions to B -> X_s gamma previously unknown.","external_url":"https://arxiv.org/abs/hep-ph/0207036","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-03T06:37:42.310428+00:00","pith_arxiv_id":"hep-ph/0207036","created_at":"2026-05-11T22:26:12.898009+00:00","updated_at":"2026-07-03T06:37:42.310428+00:00","title_quality_ok":true,"display_title":"Minimal Flavour Violation: an effective field theory approach","render_title":"Minimal Flavour Violation: an effective field theory approach"},"hub":{"state":{"work_id":"4f8a2237-4c58-46d9-a3b2-66aae66945c9","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":17,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2019-06-25T16:17:31+00:00","last_pith_cited_at":"2026-07-01T21:53:41+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-08-23T07:09:59.712350+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":4}],"polarity_counts":[{"context_polarity":"background","n":4}],"runs":{},"summary":{},"graph":{},"authors":[]}}
