The primary goal is to identify the lowest angular momenta at which perturbative treatment of chiral forces can apply. Results up to the order where the subleading two-pion exchange appears are shown. It is concluded that perturbation theory applies to all partial waves but ${}^1S_0$, ${}^3S_1 - {}^3D_1$, and ${}^3P_0$. Where it is applicable, perturbation theory with the delta-less chiral forces produces good agreeme","authors_text":"Bingwei Long, Shaowei Wu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2018-07-12T02:45:08Z","title":"Perturbative $NN$ scattering in chiral effective field theory"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.04407","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:d3d956751e20f2cbfeb95cfa513046af77370da5e10adb38616ab2e7179827b4","target":"record","created_at":"2026-05-17T23:52:52Z","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":"8423c732d25e77a858f58088b87092cb6b2431c778cf0682ffd6f2761d7478c5","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2018-07-12T02:45:08Z","title_canon_sha256":"61093fee8b1630ca363773e04cef6a98916e6c1f5ced1a300b2f4fddd5985e51"},"schema_version":"1.0","source":{"id":"1807.04407","kind":"arxiv","version":2}},"canonical_sha256":"e191a9043feebf79b0481f84e4f014936c1be40f40f0f9ba7e1928b05a8666d8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e191a9043feebf79b0481f84e4f014936c1be40f40f0f9ba7e1928b05a8666d8","first_computed_at":"2026-05-17T23:52:52.718508Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:52:52.718508Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"w1Og2PxzYKPsi/lEcK9Ozn+gsnND9zytKLaDq59qjKKNG3gp5lcsLULMMIeVAswM1h+nYV4mUtVoWh9GvKybDQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:52:52.719287Z","signed_message":"canonical_sha256_bytes"},"source_id":"1807.04407","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d3d956751e20f2cbfeb95cfa513046af77370da5e10adb38616ab2e7179827b4","sha256:2f0bc2048bfb2a9ed857fb5b6045d275ed7febdb4c1958921072ca52785294c1"],"state_sha256":"58c0b6e237ae5e0789f086b0f323d71fbfa1828bba3fbce8a82c8dcfd820ca91"}
