Abstract：
The Minimal Higgsless Model predicts the existence of new vector gauge boson W^±₁. By the process PP→W^±₁qq→W^±Z⁰qq, Z⁰→l⁺l^－, W^±→qq (l=e, μ; q is hadronized to be jets), we study the sensitivity of searching for this possible vector gauge boson in the level of generator events of signal and backgrounds, then give integrated luminosity required to discover 5σ signal as a function of W^±₁ mass. The generator for the signal PP→W^±₁qq→W^±Z⁰qq at tree level is developed with the Minimal Higgsless Model and then interfaced with PYTHIA for the parton showers and hadronization. The backgrounds are produced with
MadGraph and PYTHIA.
