    A test of QCD based on 3-jet events from Z0 decays

    Get PDF
    We present a study of 43 000 3-jet events from Z0 boson decays. Both the measured jet energy distributions and the event orientation are reproduced by second order QCD. An alternative model with scalar gluons fails to describe the data.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29222/3/0000277.pd

    Measurement of the e+e- --> bb‟\overline{b} and e+e- --> cc‟\overline{c} forward-backward asymmetries at the Z0 resonance

    No full text
    We have measured the forward-backward asymmetry in e+e−→bbande+e−→cce^+e^−→b band e^+e^−→cc processes using hadronic events containing muons or electrons. The data sample corresponds to 4100000 hadronic decays of the Z0. From a fit to the single lepton and dilepton p and pT spectra, we determine Abb=0.086±0.015±0.007andAcc=0.083±0.038±0.027 at the effective center-of-mass energy √s=91.24 GeV. These measurements yield a value of the electroweak mixing angl
