Using the ARGUS detector at the e+e− storage ring DORIS II at DESY new results on beauty and τ physics have been obtained. In particular, new measurements on fundamental constants in the Yukawa sector of the Standard Model are presented. These comprise measurements of CKM matrix elements from the study of B decays as well as determinations of properties of the τ lepton and its neutrino vτ. From semileptonic B decays ARGUS finds |Vcb|=0.050±0.008±0.007 and from [Formula: see text] mixing |Vtd|= 0.007±0.002. An analysis of the decay type τ−→π−π−π+ντ yields a τ mass of mτ=(1776.3±2.4±1.4) MeV/c2. This result also leads to an improvement of the upper limit on the [Formula: see text] at the 95% confidence level.
