Four-quark final state in W-pair production : Case of signal and background †

We discuss theoretical predictions for W -pair production and decay at LEP2 and higher energies in a form suitable for comparison with raw data. We present a practical framework for calculating uncertainties of predictions given by the KORALW and grc4f Monte Carlo programs. As an example we use observables in the ss̄cc̄ decay channel: the total four-quark… CONTINUE READING
