抜粋

A charge asymmetry has been measured in hadron jets from e+e- annihilation at energies between 52 and 61.4 geV (〈√s〉=57.6 GeV). The measured asymmetry is A=11.4%±2.2%±2.1% and is consistent with the prediction of the standard model of the electroweak theory. By using the differential cross section, lower limits of the compositeness scale in eeqq contact interactions have been determined to be typically a few TeV at 95% CL.
