In a left-right symmetric model (LRSM) along with a heavy vector-like fermion, enhancement of this order can be achieved at the bare (QCD uncorrected) level itself. We propose that a measurement of the photon polarization could be used to signal the presence of such new physics inspite of the large long distance effects.","authors_text":"Aritra Biswas, Nita Sinha, Sanjoy Mandal","cross_cats":["hep-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2017-02-16T17:20:31Z","title":"Searching for New physics in Charm Radiative decays"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1702.05059","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":"sha256:4d641e22927c8625d39fbcc04405dc18aa408a539dba727b6e3a2be9fca2cbe4","target":"record","created_at":"2026-05-17T23:57:44Z","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":"010223518ebf35105efd8946ffe4dfbaddebc8f2c9fa1ad8485004fc85d4b00c","cross_cats_sorted":["hep-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2017-02-16T17:20:31Z","title_canon_sha256":"1362dffa593e13d1b48b59f2ead58a8a198a8ce94405978d7926a02232d51b40"},"schema_version":"1.0","source":{"id":"1702.05059","kind":"arxiv","version":2}},"canonical_sha256":"46e795411d910fdd2e6bda170ad8225cf2d0ce37c041ff518ef50abeeda1047c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"46e795411d910fdd2e6bda170ad8225cf2d0ce37c041ff518ef50abeeda1047c","first_computed_at":"2026-05-17T23:57:44.645294Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:57:44.645294Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"yIInSRCfX3j2GH43C41nm9FIImRfYy1v2VmFs3WF+S5OZkFvB4WrMKSUjyoFKNU+zAf5HIrTF4IJ90naYJxgBA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:57:44.645977Z","signed_message":"canonical_sha256_bytes"},"source_id":"1702.05059","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4d641e22927c8625d39fbcc04405dc18aa408a539dba727b6e3a2be9fca2cbe4","sha256:8f187cfeb50ab9c16a880ad9499a85fb6e2a8921d24c02d66bc80d7e01a0aff1"],"state_sha256":"86b65ca958dc2bc3c55dddffb0d1a10bcefc2ef4628ca6f0573ff7094af43126"}
