Abstract:	摘要： The lifetime of the τ lepton is measured using the process e+ e- → τ+ τ- , where both τ leptons decay to 3πν(τ). The result for the mean lifetime, based on 711 fb(-1) of data collected with the Belle detector at the ϒ(4S) resonance and 60 MeV below, is τ=(290.17±0.53(stat)±0.33(syst))×10(-15) s. The first measurement of the lifetime difference between τ+ and τ- is performed. The upper limit on the relative lifetime difference between positive and negative τ leptons is \|Δτ\|/τ<7.0×10(-3) at 90% C.L. 其他題名： Phys Rev Lett 出版者： United States: American Physical Society (APS) 出版日期： 2014-01-23 出處： Physical Review Letters, 2014-01, Vol.112 (3), p.031801, Article 031801 資源來源： American Physical Society Journals 識別號： ISSN: 0031-9007 識別號： ISSN: 1079-7114 識別號： EISSN: 1079-7114 識別號： DOI: 10.1103/PhysRevLett.112.031801 識別號： PMID: 24484129
