We examine whether the deformation of a cosmic string, induced by the gravitational field of a Kerr black hole, may lead to the formation of a loop of cosmic string. The segment of the string which enters the ergosphere of a rotating black hole gets deformed and, if it is sufficiently twisted, it can self-intersect chopping off a loop of cosmic string. We find that the formation of a loop, via this mechanism, is a rare event. It will only arise in a small region of the collision phase space, which depends on the ","authors_text":"Claude Michel Viallet, Florian Dubath, Mairi Sakellariadou","cross_cats":["astro-ph","hep-ph","hep-th"],"headline":"","license":"","primary_cat":"gr-qc","submitted_at":"2006-09-21T08:57:08Z","title":"Scattering of cosmic strings by black holes: loop formation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"gr-qc/0609089","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":"sha256:783409312f0a251a61022e5540212249a5976dbc55c62d5e3fc60ea09dc5fb2a","target":"record","created_at":"2026-07-04T15:22:23Z","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":"84ae02a5175102cfec789864b0cc157f3f12d61a24bfcb2e4e6e65041cb8ea25","cross_cats_sorted":["astro-ph","hep-ph","hep-th"],"license":"","primary_cat":"gr-qc","submitted_at":"2006-09-21T08:57:08Z","title_canon_sha256":"de306be808a1d95ef6b328ee2c39a4487c031c351d623822c3e79bb27e688455"},"schema_version":"1.0","source":{"id":"gr-qc/0609089","kind":"arxiv","version":1}},"canonical_sha256":"d51743874a404d8475161b4c796e3ca1aa139a93bae9caf00ad0a1c0dad742b0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d51743874a404d8475161b4c796e3ca1aa139a93bae9caf00ad0a1c0dad742b0","first_computed_at":"2026-07-04T15:22:23.469302Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T15:22:23.469302Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"GoZsAOFleGsY/ZIRsI7jMaXsRhXBzMEGU8hQZN9eBL6ixqWbvde5RnQ0AofYqNistZZA8a9tVmP/7aWaKTbADQ==","signature_status":"signed_v1","signed_at":"2026-07-04T15:22:23.469714Z","signed_message":"canonical_sha256_bytes"},"source_id":"gr-qc/0609089","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:783409312f0a251a61022e5540212249a5976dbc55c62d5e3fc60ea09dc5fb2a","sha256:bc4e83592923084eead0b617b194ac1c0b465d7eb54dbf47b9517aa9b82b5ebd"],"state_sha256":"8b641004826979e93237ead68df760ceeba70e7348951c663c6fa9931b119b64"}
