dc.description.abstractWe report the first observation of Dþ → τþντ with a significance of 5.1σ. We measure BðDþ → τþντÞ ¼ ð1.20 0.24stat 0.12systÞ × 10−3. Taking the world average BðDþ → μþνμÞ¼ð3.74 0.17Þ × 10−4, we obtain Rτ=μ ¼ ΓðDþ → τþντÞ=ΓðDþ → μþνμÞ ¼ 3.21 0.64stat 0.43syst., which is consistent with the standard model expectation of lepton flavor universality. Using external inputs, our results give values for the Dþ decay constant fDþ and the Cabibbo-Kobayashi-Maskawa matrix element jVcdj that are consistent with, but less precise than, other determinations.tr_TR
