A measurement of the electroweak couplings of up and down type quarks using final state photons in hadronic Z0 decays
Abstract
The production rate of final state photons in hadronic Z0 decays is measured as a function of ycut = Mij2/Ecm2 the jet resolution parameter and minimum mass of the photon-jet system. Good agreement with the theoretical expectation from an O(ααs) matrix element calculation is observed. Comparing the measurement and the prediction for ycut = 0.06, where the experimental systematic and statistical errors and the theoretical uncertainties are …
