QCD Studies with Resurrected Jade Data
S. Kluth
Abstract
We report on recent studies of QCD performed using reanalysed e+e- annihilation data recorded at centre of mass energies 14<sqrt(s)<44 GeV by the JADE experiment operated 1979 to 1986 at the PETRA e+e- collider at DESY, Hamburg, Germany. The data for some event shape observables are compared to modern Monte Carlo event generators using parameter values obtained from LEP 1 data. The distribution of ln(1/x) with x=2p/sqrt(s) and p the momentum of a charged hadron is measured and compared to QCD predictions. Fits of O(alphaS2)+NLLA (resummed) QCD predictions combined with power corrections to event shape data including for the first time the sqrt(s)=14 and 22 GeV data samples are discussed.
