In this Letter, we use FWW approach to obtain the production of cosmic ultra-high energy photons and neutrinos from the collision between UHE proton with magnetic field which could be considered as the virtualphoton in the rest frame of UHE proton. We name this as $pB$ process. The threshold for the occurrence of the $pB$ process is that the combination of the Lorentz factor of proton and the strength of the ma","authors_text":"Xin-Yue Shi (USTC), Ye-Fei Yuan","cross_cats":["hep-ph","nucl-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2019-07-16T02:04:17Z","title":"Collision of ultra-relativistic proton with strong magnetic field: production of ultra-high energy photons and neutrinos"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1907.06807","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":"sha256:82c1003b828351579c4905b04b303b45982768b0cba5337d17f462ddfcc17fa7","target":"record","created_at":"2026-05-17T23:40:29Z","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":"99f4d66c25c3f0d31c22d93b8803f39c77f44632c6e61accf67d3d5a0bb4e974","cross_cats_sorted":["hep-ph","nucl-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2019-07-16T02:04:17Z","title_canon_sha256":"c5cc0d5d8295a837339ab9117ba6762bacb655b5800339452bdec10f28b0f20d"},"schema_version":"1.0","source":{"id":"1907.06807","kind":"arxiv","version":1}},"canonical_sha256":"1e4493ff56e21de1ed697383c062b70f63063e28f3be6c021597e1a9caa5d4f2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1e4493ff56e21de1ed697383c062b70f63063e28f3be6c021597e1a9caa5d4f2","first_computed_at":"2026-05-17T23:40:29.078145Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:40:29.078145Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bo/LjIvtwIZHNiEhyLuqVwkRWvhVzr7WC3Qn5uyisFWjWhXxmjRZqTGk8hrwgfe4Y5t55swi72HNnEoTPIBSAQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:40:29.078824Z","signed_message":"canonical_sha256_bytes"},"source_id":"1907.06807","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:82c1003b828351579c4905b04b303b45982768b0cba5337d17f462ddfcc17fa7","sha256:b77d89bf526b1f3432b610484b2510a5818a31c79f68223392c02d62b6a1b44f"],"state_sha256":"e2b2eaf819e26132ebdee3b7dd70e7c3a3bf67a18a52c093e51ce041667bdb72"}
