Sensitivities to the effective ALP-photon coupling $g_{a\\gamma\\gamma}$ for its mass in the range of 10 GeV $< M_{a}< 3$ TeV are obtained for the LHeC and its high-energy upgrade, FCC-eh. Comparing to existing bounds on the ALP free parameters, we find that the bounds given by $ep$ colliders are competitive and complementary to other colliders.","authors_text":"Chong-Xing Yue, Ming-Ze Liu, Yu-Chen Guo","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2019-04-24T06:54:51Z","title":"Searching for axionlike particle at future $ep$ colliders"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1904.10657","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":"sha256:81af6eda3ccb87f7122e11afc5a09f872df417f435e52c6e144c7341237b41b8","target":"record","created_at":"2026-05-17T23:40:23Z","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":"a1c13cd35eeb595252df497f8bc7c9cd9d9b5b343166e217d71a11c031c5b66d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2019-04-24T06:54:51Z","title_canon_sha256":"db6afc8ad8ab416d22e6557d4003b429be24672268822d34665b3ed0f86ee853"},"schema_version":"1.0","source":{"id":"1904.10657","kind":"arxiv","version":2}},"canonical_sha256":"401360bcc2b60049a3f736ee4826a5d0fcccae54ea9ed328bb3901ea77e39aee","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"401360bcc2b60049a3f736ee4826a5d0fcccae54ea9ed328bb3901ea77e39aee","first_computed_at":"2026-05-17T23:40:23.395640Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:40:23.395640Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"2LQBAyvDF1kcZNP33hiE/0DFCE50FGSCpskuJElSGJ9/UJvuwBJ4XUZdgFBc2bkbsMBDUIx99ZCbM4V3uuNODw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:40:23.396256Z","signed_message":"canonical_sha256_bytes"},"source_id":"1904.10657","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:81af6eda3ccb87f7122e11afc5a09f872df417f435e52c6e144c7341237b41b8","sha256:7a9cc9fc3b12d8e8789a995a8f02a508f00ab1e604e4d3cb753f47f7fe99d1d2"],"state_sha256":"f5f217cef4879c086b03c299b4e1d1b7202a9e89ef1d5d40a1a4ea8b584e8897"}
