A measurement of the tau lifetime

The tau lepton lifetime is measured using four different methods with the DELPHI detector. Three measurements using one prong decays are combined, accounting for correlations, resulting in τ τ =298 ±7 (stat.)±4 (syst.) fs while the decay length distribution of three prong decays gives π π =298±13 (s...

description	The tau lepton lifetime is measured using four different methods with the DELPHI detector. Three measurements using one prong decays are combined, accounting for correlations, resulting in τ τ =298 ±7 (stat.)±4 (syst.) fs while the decay length distribution of three prong decays gives π π =298±13 (stat)±(syst.) fs. The combined result is τ τ =298±7 fs. The ratio of the Fermi coupling constant from tau decay relative to that from muon decay is found to be 0.985±0.013, compatible with lepton universality.

Three measurements using one prong decays are combined, accounting for correlations, resulting in τ τ =298 ±7 (stat.)±4 (syst.) fs while the decay length distribution of three prong decays gives π π =298±13 (stat)±(syst.) fs. The combined result is τ τ =298±7 fs. The ratio of the Fermi coupling constant from tau decay relative to that from muon decay is found to be 0.985±0.013, compatible with lepton universality.</abstract><cop>Amsterdam</cop><pub>Elsevier B.V</pub><doi>10.1016/0370-2693(93)90409-B</doi><tpages>13</tpages><orcidid>https://orcid.org/0000-0002-4516-459X</orcidid><orcidid>https://orcid.org/0000-0003-4016-6067</orcidid><orcidid>https://orcid.org/0000-0003-3624-4480</orcidid><orcidid>https://orcid.org/0000-0003-0514-193X</orcidid><orcidid>https://orcid.org/0000-0002-2011-0851</orcidid><orcidid>https://orcid.org/0000-0002-0812-6818</orcidid><orcidid>https://orcid.org/0000-0003-1243-6808</orcidid><orcidid>https://orcid.org/0000-0001-6764-6787</orcidid><orcidid>https://orcid.org/0000-0002-1278-109X</orcidid><orcidid>https://orcid.org/0000-0002-2394-4720</orcidid><orcidid>https://orcid.org/0000-0002-0389-5706</orcidid><orcidid>https://orcid.org/0000-0001-9398-1909</orcidid><orcidid>https://orcid.org/0000-0003-3426-6248</orcidid><orcidid>https://orcid.org/0000-0002-7714-7700</orcidid><oa>free_for_read</oa></addata></record>
