The glasma model predicts that the medium initially has a large amount of high-momentum gluons but few quarks. We develop a phenomenological model based on collinear splitting and recombination of quarks and gluons for a simplified description of thermalization and chemical equilibration. We find that both could be achieved in a short time but chemical equilibration is slower than thermalization.","authors_text":"Akihiko Monnai, Berndt M\\\"uller","cross_cats":["nucl-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2014-03-28T09:17:44Z","title":"Collinear parton splitting in early thermalization and chemical equilibration"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1403.7310","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":"sha256:4522dbe9b4b3f92bc83eb85b598330c97db5c81c160cebd9fc467ab1ff1f815c","target":"record","created_at":"2026-05-18T02:55:19Z","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":"2438af70f5b5c787f5b9f98f40539cdeb69611d2d0f042de7c7e9a355542e1a5","cross_cats_sorted":["nucl-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2014-03-28T09:17:44Z","title_canon_sha256":"a51163211e0d1e487dc3e90348eb5cbfcb777b8dcadfc059ce53ad542ef33c0f"},"schema_version":"1.0","source":{"id":"1403.7310","kind":"arxiv","version":1}},"canonical_sha256":"c9493b59a7119fb3626ddd9a08e93dc2dfd39ff7640497ea98a05e3b24370c14","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c9493b59a7119fb3626ddd9a08e93dc2dfd39ff7640497ea98a05e3b24370c14","first_computed_at":"2026-05-18T02:55:19.962611Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:55:19.962611Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QYEevWgiBXzOQ/XO2SUN68GpbxJqUsJD2W7/QJarnKy5TSeZdkAP74WXXzLPozf6u3AUaQKGyMa1VEeVv75WDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:55:19.963119Z","signed_message":"canonical_sha256_bytes"},"source_id":"1403.7310","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4522dbe9b4b3f92bc83eb85b598330c97db5c81c160cebd9fc467ab1ff1f815c","sha256:22ae56f5ba6d98c8009ec3546e14fa92ae0a45cd84c09e75e340e3306d028576"],"state_sha256":"1c14ce5099e912ad752bdab29aee4b529a81f47e9a76335afb420e2600752300"}
