Contribution

It presents updated, model-independent exclusion limits on neutral vector resonances based on recent ATLAS and CMS data, improving previous bounds.

Findings

Most stringent bounds on neutral vector resonance production

Updated exclusion limits on resonance masses and couplings

Enhanced constraints on models with electroweak symmetry breaking extensions

Abstract

The model independent bounds on new neutral vector resonances masses, couplings and widths presented at arxiv:1112.0316 are updated with an integrated luminosity of L=4.7 fb^-1 from ATLAS and L=4.6 fb^-1 from CMS. These exclusion limits correspond to the most stringent existing bounds on the production of new neutral spin-1 resonances that decay to electroweak gauge boson pairs and that are associated to the electroweak symmetry breaking sector in several extensions of the Standard Model.
