Abstract
We present a first estimate of the reach of future pp colliders, the 14 TeV LHC and a futuristic 100 TeV pp collider, on a vector resonance, specifically a W′, produced via weak-boson-fusion, and decaying dominantly into tb. The analysis is motivated by Composite Higgs, Randall-Sundrum and Little Higgs scenarios, which predict the existence of vector resonances with a large coupling to W and Z longitudinal bosons. In particular, in composite Higgs models with partial compositeness, the standard Drell-Yan production channel is suppressed at large coupling while the weak-boson-fusion is enhanced and could thus provide a unique opportunity to directly test the large coupling regime of the theory. We outline a search strategy for the W′ in the weak-boson-fusion channel and present the reach of future colliders on the W′ mass vs coupling parameter space.
Highlights
Recent studies for the reach of a 100 TeV collider on vectorlike quarks, which are a general prediction of composite Higgs, Randall-Sundrum and Little Higgs models, have been presented in [11, 12], while the reach for different dijet vector resonances in the DY channel has been estimated in [13]

Summary
We will consider the two-site description derived in [7], which captures the relevant phenomenology of MCHM [1].1 The model comprises a strongly interacting sector, made up of particles which become composite at the TeV scale and a weakly coupled sector of elementary states with gauge symmetries analogous to the SM. W/Z bosons, is given by: gV = g2 cot θ2 This implies that the VBF production of the vector resonances is controlled by gV2 and is enhanced in the regime of more strongly-coupled electroweak sectors, while the DY is controlled by g22/gV2 and is suppressed for large gV couplings. VBF is a promising production mechanism to analyze at future colliders that can give complementary information to those from the searches in the DY channel and possibly give access to the large gV coupling regime. In a more natural scenario with vectorlike quarks at the ∼1 TeV scale, other promising channels to analyze in VBF are those of vector resonance decays to top partners [8]. In our study we will analyze both the narrow-width and the broad-width regimes
