At the core of any EFT is a systematic expansion of observables, which is usually obtained from a rule based on an assumption of naturalness. I discuss naturalness in the context of the relatively weak binding of nuclei, where discrete scale invariance plays a role in the emergence of complexity.","authors_text":"U. van Kolck","cross_cats":["physics.hist-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2020-03-22T19:32:58Z","title":"Naturalness in Nuclear Effective Field Theories"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2003.09974","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":"sha256:88427b327a6c065e1b6459aadadfd48d2e1db9b4985b5a1a17fa654f7a2256a5","target":"record","created_at":"2026-07-05T00:56:48Z","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":"4058ed0ee90fe2eff3139d075e6d76f47f5461aa9035aaceb84006c1f7c7931d","cross_cats_sorted":["physics.hist-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2020-03-22T19:32:58Z","title_canon_sha256":"390cbdd92ac7d4095e5a3646a2de4377ba021c49d556ee98a4ca7ec2b5531297"},"schema_version":"1.0","source":{"id":"2003.09974","kind":"arxiv","version":1}},"canonical_sha256":"5e96c858bebd7cab6f976c98e049b9c071f8e19a356be2a18a6bfa9c9c2518d3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5e96c858bebd7cab6f976c98e049b9c071f8e19a356be2a18a6bfa9c9c2518d3","first_computed_at":"2026-07-05T00:56:48.253866Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:56:48.253866Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"zfQPe3kqyAHB+vKltlS+yE1RWuKTw5XQzNY1coqojsQvAm9VUDugQpg7qUc6019AtjNlALf+eKi0idm+OyyRBw==","signature_status":"signed_v1","signed_at":"2026-07-05T00:56:48.254237Z","signed_message":"canonical_sha256_bytes"},"source_id":"2003.09974","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:88427b327a6c065e1b6459aadadfd48d2e1db9b4985b5a1a17fa654f7a2256a5","sha256:04bcc964fa29add20b18b7a5aa7104e4fe7854443301c55d688d2dde40cbb6e6"],"state_sha256":"f3df9abd66131d8172411fbc208a448f5c9a3d0b6ea49e5d3a57dd73b8157d4d"}
