Extraction of Coupling Information From $Z' \to jj$

High Energy Physics - Phenomenology 2009-10-22 v1

Abstract

An analysis by the ATLAS Collaboration has recently shown, contrary to popular belief, that a combination of strategic cuts, excellent mass resolution, and detailed knowledge of the QCD backgrounds from direct measurements can be used to extract a signal in the ZjjZ' \to jj channel in excess of 6σ6\sigma for certain classes of extended electroweak models. We explore the possibility that the data extracted from ZZ dijet peak will have sufficient statistical power as to supply information on the couplings of the ZZ' provided it is used in conjunction with complimentary results from the Z+Z' \to \ell^+ \ell^- `discovery' channel. We show, for a 1 TeV ZZ' produced at the SSC, that this technique can provide a powerful new tool with which to identify the origin of ZZ''s.
