We find that due to the Halo effect the onset of flavor transformations is pushed to smaller radii, by a few kilometers. The celebrated phenomenon of the spectral split is found to be robust under the present inclusion of the Halo effect.","authors_text":"Mark Paris, Shashank Shalgar, Vincenzo Cirigliano","cross_cats":["astro-ph.HE"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-07-18T18:00:00Z","title":"Collective neutrino oscillations with the halo effect in single-angle approximation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.07070","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:f3408e7eba936e2eba9b39f74907071bea9734c122b7c9afcafbbc4944a9e117","target":"record","created_at":"2026-05-17T23:59:52Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"737c2354e61754ec391f22aa4785830a6503a32b1eb3227a6bcdbf90c57cc9e9","cross_cats_sorted":["astro-ph.HE"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-07-18T18:00:00Z","title_canon_sha256":"902235b1c874804d788cbdf2acce238b053c9ae8753021d050a0a531c9467be3"},"schema_version":"1.0","source":{"id":"1807.07070","kind":"arxiv","version":1}},"canonical_sha256":"15e26e8e08f6e1f7e21254b6d3aeab086eebf2a04f60d821929eaaa910fe2d6d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"15e26e8e08f6e1f7e21254b6d3aeab086eebf2a04f60d821929eaaa910fe2d6d","first_computed_at":"2026-05-17T23:59:52.166821Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:59:52.166821Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"eSKzau2x5PIAFZg1yaGDkpNyjnDgp1s0XnhXAWG55oVksvp3hb/iq1/tjm3hrslKYLRiGUmaNhtiWAEQnQE0AA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:59:52.167309Z","signed_message":"canonical_sha256_bytes"},"source_id":"1807.07070","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f3408e7eba936e2eba9b39f74907071bea9734c122b7c9afcafbbc4944a9e117","sha256:05593c3c5e5c4333a53374af98a7a0842134a478b6391c98c6008c062a0d41a6"],"state_sha256":"72084505af5cdf48ddec3e47db0e40b6f0bb612d1f1b57a9b87707f944bc50ae"}
