In particular, we consider the process t-tilde_1 -> t chi^0_1 (with chi^0_1 being the lightest neutralino) followed by t -> bW. It is shown that, by the study of the angular distribution of the bottom quark (as well as the production cross section of the top squark), properties of chi_1^0 can be extracted. We also discuss that, if chi^0_1 is gaugino-like, the neutralino mixing parameters (i.e., the so-called mu","authors_text":"Ryuichiro Kitano, Shufang Su, Takeo Moroi","cross_cats":[],"headline":"","license":"","primary_cat":"hep-ph","submitted_at":"2002-08-15T06:51:58Z","title":"Top-Squark Study at a Future e^+e^- Linear Collider"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/0208149","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":"sha256:992b6ac4a4204ae2d9786ebd314b52e960e92342e4bdd642de5bc49e789b69dc","target":"record","created_at":"2026-05-18T04:19:23Z","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":"989903269869297c293eba4c48977c41a9aa69d043f522b774ee5e1955121fff","cross_cats_sorted":[],"license":"","primary_cat":"hep-ph","submitted_at":"2002-08-15T06:51:58Z","title_canon_sha256":"36c463e0b9cf9464d6901a9a4834a0fcf79f0dbb63bb8920141ef455856fc3a2"},"schema_version":"1.0","source":{"id":"hep-ph/0208149","kind":"arxiv","version":2}},"canonical_sha256":"e06c5ad1c00016857823e49cf21c5c21efe8a24abacfd22d319c508f12816ef0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e06c5ad1c00016857823e49cf21c5c21efe8a24abacfd22d319c508f12816ef0","first_computed_at":"2026-05-18T04:19:23.607211Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:19:23.607211Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hF2vvh1qZxerEC5HbW14TRBvFBScPlR5JHZatNrZmrmlyCA0706YCzfC3ydDuHmbtnQ7XsfRoank9w04y3LtAA==","signature_status":"signed_v1","signed_at":"2026-05-18T04:19:23.607628Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-ph/0208149","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:992b6ac4a4204ae2d9786ebd314b52e960e92342e4bdd642de5bc49e789b69dc","sha256:b4bcb1cb82c31e4af2d0f00047855013bfdcbc2cac12518d2abc6206a74b61ef"],"state_sha256":"bdae2ef0435ab434aa91adaeda29982bcd0034084fa7a2a334ac802a62af7d4f"}
