Distinguishing new physics scenarios with polarized electron and positron beams
Abstract
Contactlike nonstandard interactions can be revealed only through deviations of observables from the standard model predictions. We consider a number of such nonstandard scenarios, and discuss their identification as sources of deviations in fermion-pair production processes at the International Linear Collider, if they were observed. We emphasize the role of e- and e+ polarization in enhancing the identification reaches.
