This note presents the prospects of searches for new heavy resonances decaying to diboson (WW) and measurements of electroweak WW/WZ production via vector boson scattering (VBS) in association with a high-mass dijet system in the ℓνqq final states (W→ℓν, W/Z→ qq). The prospects are presented for an integrated luminosity of 15 ab-1 of proton-proton (pp) collisions at √(s)=27 TeV with an ATLAS-like detector simulated in the Delphes framework. The cross-section measurement of the electroweak WW/WZ production in VBS processes is expected to reach the precision of ∼2-3%, improving the expected accuracy at the HL-LHC by a factor of 2. Prospects are presented also for the separation of the longitudinal component of the electroweak WW/WZ production, showing the expected significance of ∼3σ is reached with 3 ab-1 for the single ℓ νqq channel and ∼5σ for all the semi-leptonic channels combined. The diboson resonance searches are interpreted for sensitivity to a simplified phenomenological model with a heavy gauge boson. With 15 ab-1 of pp data, the discovery reach for the new resonance is extended to 8 TeV.
