New Interactions in Neutral Current Processes

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

Measurements of neutral current processes off the ZZ-peak are sensitive probes of new interactions, which may be induced by the exchange of new particles such as leptoquarks or extra ZZ'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.
