We make no simplifying assumptions about the neutralino nor about sfermion masses and mixings other than the absence of explicit CP--violating terms. The expressions should be particularly useful in computing the neutralino WIMP relic abundance without the usual approximation of partial wave expansion.","authors_text":"Leszek Roszkowski, Roberto Ruiz de Austri, Takeshi Nihei","cross_cats":[],"headline":"","license":"","primary_cat":"hep-ph","submitted_at":"2002-02-02T08:11:59Z","title":"Exact Cross Sections for the Neutralino WIMP Pair-Annihilation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/0202009","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:c04c9a704a8881b5b2f64d571f8985e498939a78ef158534f83e45da32ffb756","target":"record","created_at":"2026-05-18T02:36:38Z","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":"86b4ef1b7d919f5b80b3eba78b0afb6c1081f395d4a35c2353ef70500adf2c70","cross_cats_sorted":[],"license":"","primary_cat":"hep-ph","submitted_at":"2002-02-02T08:11:59Z","title_canon_sha256":"e525ba300fd415c756bd562f8ae8631949a09dd04b631002bf471291b67a8a1d"},"schema_version":"1.0","source":{"id":"hep-ph/0202009","kind":"arxiv","version":2}},"canonical_sha256":"42470bba0997126b139fb6399d2ace81f10f5904050e3a4584196742ce6c1c17","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"42470bba0997126b139fb6399d2ace81f10f5904050e3a4584196742ce6c1c17","first_computed_at":"2026-05-18T02:36:38.579510Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:36:38.579510Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VlUY0AW2FmCqG96l03ugbxoSV8V3pP17o9xUkwceJzUEYkZA/C8B5McfPZaKwDMFasH7+tsbiDCL3LUpNrcHCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:36:38.580107Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-ph/0202009","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c04c9a704a8881b5b2f64d571f8985e498939a78ef158534f83e45da32ffb756","sha256:13b89890ded86ab2e154a06ea298482a72973209642dcfd77fc7679f3186801e"],"state_sha256":"640124b2e69b642d935168c336afb1d9250c5fd44ae406399968b649a539d76e"}
