Abstract:	摘要： We report a measurement of the branching fraction ratios R(D)(()()) of (B) over bar -> D-(())tau(-)(nu) over bar (tau) relative to (B) over bar -> D-(())l(-)(nu) over barl (where l = e or mu) using the full Belle data sample of 772 x 10(6)B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The measured values are R(D) = 0.375 +/- 0.064(stat) +/- 0.026(syst) and R(D) = 0.293 +/- 0.038 (stat) +/- 0.015 (syst). The analysis uses hadronic reconstruction of the tag-side B meson and purely leptonic t decays. The results are consistent with earlier measurements and do not show a significant deviation from the standard model prediction. 出版者： American Physical Society (APS) 出版日期： 2015-10-26 出處： Physical Review D, 2015-10, Vol.92 (7) 識別號： ISSN: 1550-7998 識別號： DOI: 10.1103/physrevd.92.072014
