We employ Skyrme force models for the description of in-medium nucleon-nucleon, nucleon-Lambda hyperon ($N\\Lambda$), and Lambda-Lambda ($\\Lambda\\Lambda$) interactions. A phenomenological finite-range force for the $\\Lambda\\Lambda$ interaction is considered as well. Equation of state (EoS) of NS matter is obtained in the framework of density functional theory, and Tolman-Oppenheimer-Volkoff equations are solved to obtain the mass-radius relations of NSs. It has been generally known that the existence of hyperons in the NS matter is ","authors_text":"Chang Ho Hyun, Chang-Hwan Lee, Kyujin Kwak, Yeunhwan Lim","cross_cats":["astro-ph.SR","hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2014-12-18T05:31:14Z","title":"Hyperon Puzzle of Neutron Stars with Skyrme Force Models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1412.5722","kind":"arxiv","version":2},"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:bd077695ea030ea3c5618784a8f7dd195f397d85583b7ea4476f938ceba2ebc6","target":"record","created_at":"2026-05-18T01:21:55Z","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":"299cee129318ff8008b75fd585e1ae2d3818253a4a45b73f9221c4ae2c16fbd6","cross_cats_sorted":["astro-ph.SR","hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2014-12-18T05:31:14Z","title_canon_sha256":"e6485590dc7bdbba975d5ed0d547f345bbb2c5f88fe7adf39a356d4a763a9cad"},"schema_version":"1.0","source":{"id":"1412.5722","kind":"arxiv","version":2}},"canonical_sha256":"cb5d540366fc3e6247ca2a07729b59d1f27ac35e8cc1829e69633d06e79f3a22","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cb5d540366fc3e6247ca2a07729b59d1f27ac35e8cc1829e69633d06e79f3a22","first_computed_at":"2026-05-18T01:21:55.788641Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:21:55.788641Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"q8gQZuUZ1NhzOyZTWbd8dOAC6Li72qviPzh1xARQaa5hnGe32TXGQWRzR+9YNNTkUqjG2Y4dJGBpOU/iTrCOAw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:21:55.789378Z","signed_message":"canonical_sha256_bytes"},"source_id":"1412.5722","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bd077695ea030ea3c5618784a8f7dd195f397d85583b7ea4476f938ceba2ebc6","sha256:515bbc1ad7013cc8db72a6f0e29bf13707161e88688d5e0438c84d9488393e18"],"state_sha256":"ac3aece66cf16d994e4e73299d1f21943d18aaedd10715a077069f4e1e137510"}
