Combining searches of Z' and W' bosons

Understand

We study in a model-independent way new neutral and charged vector bosons that could give observable signals with leptonic final states at the LHC.

• We show, in particular, that a charged vector W' decaying into lepton plus neutrino is accompanied by at least an extra neutral vector boson Z', nearly degenerate with the charged one.
• Conversely, a Z' boson with significant isospin violation cannot exist without a companion W'.
• To take advantage of these generic correlations, we perform a combined analysis of LHC data in the dilepton and lepton-plus-missing-energy channels, which allows us to improve the limits from independent analyses.
