Measurement of C-Parameter and Determinations of alpha_s from C-Parameter and Jet Broadening at PETRA Energies

P. A. Movilla Fernández, O. Biebel, S. Bethke +1

e^+e^- annihilation data recorded by the JADE detector at PETRA were used to measure the C-parameter for the first time at sqrt{s}= 35 and 44 GeV. The distributions were compared t…
