Bounds on Anomalous Gauge Couplings from Past and Near Future Experiments: The211 Role of the Different Measurements

摘要

The authors analyze the bound on the set of four 'non-blind' anomalous gauge211u001ecouplings that will be derived, in absence of deviations from the Standard Model 211u001epredictions, from near future measurements at LEP2 and at the TEVATRON. The 211u001ebounds are obtained by combining these negative results with those already 211u001eavailable from LEP1 and from atomic parity violation experiments. In this 211u001eprocess, the information coming from LEP2 is treated using a recently proposed 211u001e('Z-peak subtracted') theoretical approach. This makes it easier to identify the 211u001especific role that the different experiments play in this determination, in the 211u001espirit of a recent previous investigation for the set of three 'blind' couplings.
