Present bounds on new neutral vector resonances from electroweak gauge boson pair production at the LHC

Abstract

Several extensions of the standard model predict the existence of new neutral spin-1 resonances associated with the electroweak symmetry breaking sector. Using the data from ATLAS (with integrated luminosity of L = 1.02 fb − 1 ) and CMS (with integrated luminosity of L = 1.55 fb − 1 ) on the production of W + W − pairs through the process p p → ℓ + ℓ ' − E̸ T , we place model independent bounds on these new vector resonances masses, couplings, and widths. Our analyses show that the present data exclude new neutral vector resonances with masses up to 1-2.3 TeV depending on their couplings and widths. We also demonstrate how to extend our analysis framework to different models with a specific example.
