Specifically, the essentials of continuation of the spacelike perturbative results into the timelike domain are elucidated. The derivation of a general form of the commonly employed approximate expression for the R-ratio (which constitutes its truncated re-expansion at high energies) is delineated, the appearance of the pertinent $\\pi^2$-terms is expounded, and their basic features are examined. It is demonstrated that the validity range of such approximation is strictly ","authors_text":"A.V.Nesterenko","cross_cats":["hep-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2017-07-03T17:43:27Z","title":"Electron-positron annihilation into hadrons at the higher-loop levels"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1707.00668","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:ea71e1b63504ee0004acf7e5f0fde98146ce814e601b84c27f6b446f422f71f0","target":"record","created_at":"2026-05-18T00:27:48Z","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":"3ccd7419578f2debfb64f502ac86adb3a976caf2c6a96bd8766d1bc2eccd5cea","cross_cats_sorted":["hep-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2017-07-03T17:43:27Z","title_canon_sha256":"03e06163ac30cc42ba17266e6d47607353c727e800dbbc7a796dda106e99015e"},"schema_version":"1.0","source":{"id":"1707.00668","kind":"arxiv","version":2}},"canonical_sha256":"68d47000455a964ab5e96804ec36ea2cfff85efbcde5914a72477b43908fceec","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"68d47000455a964ab5e96804ec36ea2cfff85efbcde5914a72477b43908fceec","first_computed_at":"2026-05-18T00:27:48.342371Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:27:48.342371Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"D+SH2Q7gwQXPwnkL95Ixl2V/ngJW91zMidXVzT52cO5b8lh42rT92I+35GKE49oR671W0Q5GuiHqozatYzrdDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:27:48.342851Z","signed_message":"canonical_sha256_bytes"},"source_id":"1707.00668","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ea71e1b63504ee0004acf7e5f0fde98146ce814e601b84c27f6b446f422f71f0","sha256:032fbdff86e55a416dab37daa88a20d34e3d73fcab513d515fb7c1ff46b8a53f"],"state_sha256":"4a5a616c78af619abc48b3974ea74e9b956129fe1329752502024aa35d11b754"}
