Search for W$' \rightarrow$ tb in the hadronic final state in proton-proton collisions at 8 TeV with the ATLAS detector

We present a model independent search for a $W'$ boson in the $W' \rightarrow t\bar{b} \rightarrow q\bar{q'} b\bar{b}$ final state using $20.3 fb^{-1}$ of 8 TeV data collected by the ATLAS detector from the Large Hadron Collider (LHC) in 2012. This analysis searches for both left- and right-handed chiral $W'$ bosons in the mass range of 1.5 to 3.5 TeV. Reconstructing the hadronically decaying top-quark is done using jet substructure tagging techniques. Limits are set on the ratios of coupling strength $g'$ to the Sequential Standard Model coupling $g_{SM}$.
