The particle physics and cosmology associated with other global symmetries can also be significantly changed.","external_url":"https://arxiv.org/abs/hep-th/9202003","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-24T00:53:40.988658+00:00","pith_arxiv_id":"hep-th/9202003","created_at":"2026-05-11T12:01:05.523683+00:00","updated_at":"2026-05-24T00:53:40.988658+00:00","title_quality_ok":true,"display_title":"Planck-Scale Physics and the Peccei-Quinn Mechanism","render_title":"Planck-Scale Physics and the Peccei-Quinn Mechanism"},"hub":{"state":{"work_id":"f8ddb54f-5c2b-4b8e-b911-a2fb2a586804","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":14,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2020-03-02T18:51:00+00:00","last_pith_cited_at":"2026-05-21T13:25:27+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":"2026-06-02T13:24:47.933009+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":11}],"polarity_counts":[{"context_polarity":"background","n":11}],"runs":{},"summary":{},"graph":{},"authors":[]}}
