In the attempt to fully profile a $Z'$ boson accessible at the Large HadronCollider (LHC), we study the sensitivity of di-lepton (for the electron, muonand tauon cases) and di-quark (for the case of the heavy flavours, $t$ and,possibly, $b$) samples to the nature of the new gauge state, for aone-dimensional class of non-exotic $Z'$ bosons. Assuming realistic final statereconstruction efficiencies and error estimates, we find that, depending on theCERN collider energy and luminosity, the best chances of extracting the $Z'$quantum numbers occur when two or more of these channels are simultaneouslyexplored, as none of them separately enables one to fully probe the parameterspaces of the aforementioned models. Effects of Standard Model (SM) backgroundas well interferences between this and the various $Z'$ signals have beenaccounted for. A complete study of cross sections and asymmetries (both spatialand spin ones) makes clear the need for complementarity, especially for theirdisentanglement over the full parameter space.
