Two opposite charged new heavy gauge boson pair production at the Large Hadron Collider (LHC) is presented in this paper. These bosons are known as \(W^{'}\) boson due to the reason that it is the heavy version of Standard Model's weak force carrier, the \(W\) boson. The production cross section and decay width in proton-proton (\(pp\)) collision at \sqrts~= 8 TeV are calculated for different masses and coupling strengths of \(W^{'}\). Efficiencies for different signal regions and branching ratios for different decay channels are computed. In this study, the pair production (\(W^{'^{+}}W^{'^{-}}\)) is considered in emerging new physics as a result of \(pp\) collision at \sqrts~= 8 TeV at the LHC with final state containing two tau (\(\tau\)) leptons and two neutrinos (each \(W^{'}\) decay to \(\tau\) and its neutrino). The event selection efficiency similar to the CMS experiment is used for the mass of \(W^{'}\) to set lower limits for different coupling strengths of \(W^{'}\) and results are presented in this work. For heavy gauge bosons, when coupling strength is similar to that of Standard Model's \(W\) boson, the mass of \(W^{'}\) below 305 GeV are excluded at confidence level of \(95\%\).
