Abstract

21 pp. (1978)., Decays of the heavy lepton τ have now been observed in e+e− ‐ collisions at the energy of the ψ′‐resonace, which results in an improved mass determination Mτ=1.807±0.020 GeV. For the τ‐life‐time a new upper limit of ττ?3.5⋅10−12 sec. is given. The evidence for the decay τ→νπρ has been strengthened, and the πρ‐system is found to be in an S‐wave state with JP=1+, proving the axial vector component in the leptonic coupling of the τ to hadrons. The branching ratio is given with BR(τ−→νπ−ρ0) =0.050±0.015. The total hadronic cross section agrees within errors with the quarksum rule including QCD‐corrections. The production and decay distributions of the decay J/ψ→f0γ have been measured and found to agree well with a QCD calculation based on the exchange of two gluons.

Abstract

Three different mechanisms are discussed which excite synchro-betatron resonances: the beam-beam interaction at a crossing angle, a dispersion at a cavity and transverse fields with a longitudinal gradient. Experimental results from DORIS and PETRA are shown.

Abstract

Physics reports 276(5-6), 224 - 405 (1996). doi:10.1016/S0370-1573(96)00008-7, The impact of the ARGUS experiment to elementary particle physics is reviewed. More than ten years of data taking has allowed ARGUS to contribute significantly to our understanding of beauty and charmed hadrons, τ Leptons, ϒ mesons, ϒϒ interactions and fragmentation processes. In particular the ARGUS measurements of CKM matrix elements opened up a new window on the Standard Model., Published by Elsevier Science, North-Holland, Amsterdam [u.a.]
