Abstract:	摘要： We report a new sensitive search for CPT violation, which includes improved measurements of the CPT-violating parameter z and the total decay-width difference normalized to the averaged width DeltaGamma_d/Gamma_d of the two Bd mass eigenstates. The results are based on a data sample of 535 x 10^6 BBbar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. We obtain Re(z) = [+1.9 +/- 3.7 (stat) +/- 3.3 (syst)] x 10^{-2}, Im(z) = [-5.7 +/- 3.3 (stat) +/- 3.3 (syst)] x 10^{-3}, and DeltaGamma_d/Gamma_d = [-1.7 +/- 1.8 (stat) +/- 1.1 (syst)] x 10^{-2}, all of which are consistent with zero. This is the most precise single measurement of these parameters in the neutral B-meson system to date. 7 pages, 3 figures, 2 tables, LaTeX; addition of supplemental information, corrections of typos, results unchanged 出版者： American Physical Society (APS) 出版日期： 2012-04-24 出處： Physical Review D, 2012-04, Vol.85 識別號： ISSN: 1550-7998 識別號： EISSN: 1550-2368 識別號： DOI: 10.48550/arxiv.1203.0930 識別號： DOI: 10.1103/physrevd.85.071105
