New Interactions in Neutral Current Processes
Dieter Zeppenfeld, Kingman Cheung
Abstract
Measurements of neutral current processes off the Z-peak are sensitive probes of new interactions, which may be induced by the exchange of new particles such as leptoquarks or extra Z's. This talk reviews the phenomenology of extra interactions in four-fermion processes and updates a global fit to contact terms in the neutral current sector.
