In the framework of high energy physics, the physical nature of this field is discussed and its interaction with ordinary matter is studied and explicitly calculated. It is shown that this coupling is generically too strong to be compatible with local tests of gravity. A possible way out, the chameleon effect, is also briefly investigated.","authors_text":"Jerome Martin","cross_cats":["gr-qc","hep-ph","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph","submitted_at":"2008-03-28T09:40:37Z","title":"Quintessence: a mini-review"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0803.4076","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:d28ef1fbaca5689481d56760e7838a5847c78958245f8ccaf00ebbc2d3c3882f","target":"record","created_at":"2026-07-04T15:44:45Z","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":"bb1686f6297554b3684ff63529c90d2ec75255f197d68fe09ffbf5640d11364c","cross_cats_sorted":["gr-qc","hep-ph","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph","submitted_at":"2008-03-28T09:40:37Z","title_canon_sha256":"e0e303593bda93bb3d6b820a0ee7567bd01279a4a96092fe6ffd91be3291a37e"},"schema_version":"1.0","source":{"id":"0803.4076","kind":"arxiv","version":1}},"canonical_sha256":"a07428b81d22dca633291fd5d73a9be75e5ecaf41eee30eda2f3b132b29c851b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a07428b81d22dca633291fd5d73a9be75e5ecaf41eee30eda2f3b132b29c851b","first_computed_at":"2026-07-04T15:44:45.727206Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T15:44:45.727206Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Kl9IbEXWm0xWJoDkIglD9wjJN/+kEyaGWo09IHaj7Q2hcLPK3lDEPvrX7+ezYRf9oNvxinnM7s63QMUo8hxGDw==","signature_status":"signed_v1","signed_at":"2026-07-04T15:44:45.727588Z","signed_message":"canonical_sha256_bytes"},"source_id":"0803.4076","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d28ef1fbaca5689481d56760e7838a5847c78958245f8ccaf00ebbc2d3c3882f","sha256:4f344fda7efae387fa7675bf8360efebe5907dbe5797d67a994712721e6408f1"],"state_sha256":"efcacfc67c4d23dd522f83e29cbaf8dddd51ce5bc12ed551adefa3d83a113543"}
