We especially focus on the 4-quark vector couplings and the 8-quark vector NJL couplings and allocate a region in this parameter subspace where hybrid stars with masses larger than $2M_\\odot$ exist.","authors_text":"Sanjin Beni\\'c","cross_cats":["astro-ph.HE","hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2015-03-31T17:56:10Z","title":"Multiquark interactions and heavy hybrid stars"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1503.09145","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:ebce932617fbe5623d7492ef66c5aa864247d32719770b4ab5ed6d3b8f0773f0","target":"record","created_at":"2026-05-18T02:19:51Z","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":"0c089a7303c0ec48d73b511060436bdc9e76a6509fe65925c9fa574aeaf6abb1","cross_cats_sorted":["astro-ph.HE","hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2015-03-31T17:56:10Z","title_canon_sha256":"e72d7f132c8d3e1c3746cf09b386ee02ee6ccc534899d2be29fea75fbcb06cc0"},"schema_version":"1.0","source":{"id":"1503.09145","kind":"arxiv","version":1}},"canonical_sha256":"dc773a61d2f95ec6e81edbcfa0dc86827dc3adaf1e2148bc2ae8d3c713719044","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dc773a61d2f95ec6e81edbcfa0dc86827dc3adaf1e2148bc2ae8d3c713719044","first_computed_at":"2026-05-18T02:19:51.295354Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:19:51.295354Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0ymeeXxDq408rBy01h8dCY1XvhJ1d1btZ7GwCq7amUUlMy4yDWU1BejGChXk8C63nJccbARfqGYVSHg+vKKqAA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:19:51.295911Z","signed_message":"canonical_sha256_bytes"},"source_id":"1503.09145","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ebce932617fbe5623d7492ef66c5aa864247d32719770b4ab5ed6d3b8f0773f0","sha256:441abfaf302e8753b1d192b29f65cc5d0bf916d9bf25f0c1bbb67896cca5ec16"],"state_sha256":"e4c08d1dce12714255acb9b47d14b2cc06f1d636b51d9875a1600e2fdba8656f"}
