We study the use of final state particle pseudorapidity for measurements of s-channel resonances at the LHC. Distinguishing the spin of an s-channel resonance can, in principle, be accomplished using angular distributions in the centre-of-mass frame, possibly using a centre-edge asymmetry measurement, A_CE. In addition, forward-backward asymmetry measurements, A_FB, can be used to distinguish between models of extra neutral gauge bosons. In this note we show how these measurements can be improved by using simple methods based on the pseudorapidity of the final state particles and present the expected results for A_FB and A_CE for several representative models.
