摘要：

e(+)e(-) annihilation data recorded by the JADE detector at PETRA were used to measure the C-parameter for the first time at root s = 35 and 44 GeV. The distributions were compared to a resummed QCD calculation. In addition, we applied extended resummed calculations to the total and wide jet broadening variables, B-T and B-W. We combined the results on Lu, with those of our previous study of differential 2-jet rate, thrust, and heavy jet mass, obtaining alpha(s)(35 GeV) = 0.1448(-0.0070)(+0.0117) and alpha(s)(44 GeV) = 0.1392(-0.0074)(+0.0105). Moreover power corrections to the mean values of the observables mentioned above were investigated considering the Milan factor and the improved prediction for the jet broadening observables. Our study, which considered e(+)e(-) data of five event shape observables between root s = 14 and 183 GeV, yielded alpha(s)(M-Z0) = 0.1177(-0.0034)(+0.0035).
