In Higgsless models, new vector resonances appear to restore the unitarity of the WlWl scattering amplitude without the Higgs boson. In the ideal delocalized three site Higgsless model, one of large production cross section of the neutral vector resonance (Z') at the Large Hadron Collider is the W-associated production, pp → Z'W± → W ±W±W±. Although the dileptonic decay channel, l?l'v'jj, is experimentally clean to search for the Z' signals, it is difficult to reconstruct the Z' invariant mass due to the two neutrinos in the final state. We study collider signatures of Z' using the MT2-Assisted On-Shell (MAOS) reconstruction of the missing neutrino momenta. We show the prospect of the Z' mass determination in the channel, l?l'v'jj, at the Large Hadron Collider.
