The analysis exploits the highly polarized SLC electron beam to extract these quantities directly from a measurement of the τ decay spectra, using the 1993–1995 SLD data sample of 4328 e+e-→Z0→τ+τ- events. From the decays τ→πντ and τ→ρντ we obtain a combined value hντ = -0.93±0.10±0.04. The leptonic decay channels yield combined values of ρ = 0.72±0.09±0.03, ξ = 1.05±0.35±0.04, and δξ = 0.88±0.27±0.04.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0031-9007","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA00773679","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"4691"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1997-06-23","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"25","bibliographicPageEnd":"4696","bibliographicPageStart":"4691","bibliographicVolumeNumber":"78","bibliographic_titles":[{"bibliographic_title":"Physical Review Letters"},{"bibliographic_title":"Physical Review Letters"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevLett.78.4691","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1103/PhysRevLett.78.4691","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"PhysRevLett_78_4691.pdf","filesize":[{"value":"163.4 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2008492/files/PhysRevLett_78_4691.pdf"},"version_id":"46e682bf-c489-4cfb-a83f-45fcf84639fe"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"18766"},"item_title":"Measurement of the τ Neutrino Helicity and Michel Parameters in Polarized e+e- Collisions","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2008492","relation_version_is_last":true,"title":["Measurement of the τ Neutrino Helicity and Michel Parameters in Polarized e+e- Collisions"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-22T03:48:26.389435+00:00"}
