Besides being able to describe the angular correlation functions of meson-meson pairs, a large improvement for the angular correlations of baryon-baryon and antibaryon-antibaryon is achieved. We further find that the AMPT model with new quark coalescence provides an even better description on the anti-correlation feature of baryon-baryon correlations observed in the experiments. We also extend the study to p-Pb collisions at $\\sqrt{s}= 5.02$ TeV and obtained similar","authors_text":"Jinhui Chen, Liuyao Zhang, Song Zhang, Yugang Ma, Ziwei Lin","cross_cats":["nucl-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2018-08-31T09:22:34Z","title":"Two-particle angular correlations in pp and p-Pb collisions at LHC energies from a multi-phase transport model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.10641","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:c924878b7b0b9b2704f9b62beee58bef8c53b96109c84983e18a603518e2bc54","target":"record","created_at":"2026-05-18T00:04:47Z","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":"606aede09243e40adc7e52b7f517b0e8fef2c23010a0e57659cdfbd9ad807c84","cross_cats_sorted":["nucl-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2018-08-31T09:22:34Z","title_canon_sha256":"aa90ef93de6b89c3f2857ee690853bddea94d716ae6696d6cb7700b2ed79d020"},"schema_version":"1.0","source":{"id":"1808.10641","kind":"arxiv","version":1}},"canonical_sha256":"56bcea9d35883ff600776cb2c61ce673dd5bfe7bfe4b58a43072dc0481988c1a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"56bcea9d35883ff600776cb2c61ce673dd5bfe7bfe4b58a43072dc0481988c1a","first_computed_at":"2026-05-18T00:04:47.968196Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:04:47.968196Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rGD+pSNffrO/8o+1/jbvY5B01mBd1WBrfjdwvs0QocaKUmP8SlzgOWVtIritpH6w2p6r5N5YTwhDykzF39d7AA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:04:47.968904Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.10641","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c924878b7b0b9b2704f9b62beee58bef8c53b96109c84983e18a603518e2bc54","sha256:830977ff51bb147971292e40baa678de1696b8a32fa34339e900c8c7da79e1fc"],"state_sha256":"5824eb32b956b3c9f5a074f6f7684bdd37a8253849cc4f8ff58df9bbb3c5deb8"}
