The physical form factors $G_{C,M,Q}(Q^2)$ of $\\rho$-meson as well as the charged square radius $\\langle r^2\\rangle$, the magnetic moment $\\mu$ and the quadrupole moment $\\bar Q$ are calculated, which describe the behaviors of EMFFs at zero momentum transfer. Using the type-II replacement, we find that the zero-mode does contribute zero to the matrix element $S_{00}^+$. It is found that the ``$M\\to M_{0}$\" replacement improves angular condition remarkably, which","authors_text":"Shuai Xu, Xiao-Nan Li, Xing-Gang Wu","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ph","submitted_at":"2025-05-05T07:27:11Z","title":"The $\\rho$-meson electromagnetic form factors within the light-front quark model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2505.02419","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":"sha256:4f6389e9323faedaa537937452efc7aaff4a0d8e35d67d0aece38860f1f5fe01","target":"record","created_at":"2026-07-05T10:58:36Z","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":"4f21810fc8277d84c4d21a2e4f875c88d6d76a544a4b1e93df5237aa0747023f","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ph","submitted_at":"2025-05-05T07:27:11Z","title_canon_sha256":"08e0e061f4cdae81e36c76e23e41f880e0a0287d0a28e492bbc7f9893264462c"},"schema_version":"1.0","source":{"id":"2505.02419","kind":"arxiv","version":1}},"canonical_sha256":"021176b3aa9f9ba4f2a50e926e7cdece0db8a2173ab7ea13c6570ab2a1e23edf","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"021176b3aa9f9ba4f2a50e926e7cdece0db8a2173ab7ea13c6570ab2a1e23edf","first_computed_at":"2026-07-05T10:58:36.732257Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:58:36.732257Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"KSpcRzmD5fYs1HuIiCM0VxIPQ019N8Io6FmMXpQooIc+XOLwkQjOcE3F1+Dsrfrhtj2pSKkmJybsvUYiUPgaCA==","signature_status":"signed_v1","signed_at":"2026-07-05T10:58:36.732831Z","signed_message":"canonical_sha256_bytes"},"source_id":"2505.02419","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4f6389e9323faedaa537937452efc7aaff4a0d8e35d67d0aece38860f1f5fe01","sha256:73b7bbdd353d9473b195d405937db255e97281d7927d7feb345946d43191af76"],"state_sha256":"43acb55a039115ea22f747946388d48135ee3c4941f271c6290773c2e3b32fde"}
