We study the LHC signatures of new gauge bosons in the gauge-invariant minimal Higgsless model. It predicts an extra pair of W1 and Z1 bosons which can be as light as ∼400  GeV and play a key role in the delay of unitarity violation. We analyze the W1 signals in pp→W0Z0Z0→jj4ℓ and pp→W0Z0jj→ν3ℓjj processes at the LHC, including the complete electroweak and QCD backgrounds. We reveal the complementarity between these two channels for discovering the W1 boson, and demonstrate the LHC discovery potential over the full range of allowed W1 mass.
