We explore the physics of a new neutral gauge boson, ($Z^\prime$), coupling to only third-generation particles with mass near electroweak boson poles. A $Z^\prime$ produced by top quarks and decaying tau leptons is considered. With simple search strategy inspired existing analyses standard model production in association quarks, we show that Large Hadron Collider has good exclusionary power over parameter space even at advent high-luminosity era. It shown $t\bar{t}Z^\prime$ process allows one place limits on right-handed couplings preferentially couples third generation fermions, which are present very weakly constrained.
