The Forward-Backward Asymmetry (AFB) in Z physics is commonly only perceived as the observable which possibly allows one to interpret a Z signal by distinguishing different models of such (heavy) spin-1 bosons. In this article, we examine the potential of AFB in setting bounds on or even discovering a Z at the Large Hadron Collider (LHC) and show that it might be a powerful tool for this purpose. We analyze two different scenarios: Z s with a narrow and wide width, respectively. We find that in both cases AFB can complement the cross section in accessing Z signals.
