Discriminating spin through quantum interference

Year: 2008

Type: article

Abstract: Many of the proposed solutions to the hierarchy and naturalness problems postulate new ``partner'' fields to the standard model particles. Determining the spins of these new particles will be critical in distinguishing among the various possible standard model extensions, yet proposed methods rely on the underlying models. We propose a new model-independent method for spin measurements which takes advantage of quantum interference among helicity states. We demonstrate that this method will be able to discriminate scalar particles from higher spin states at a linear collider.
