RESUMO
We study three different variables that can be useful for Z' model discrimination: the forward-backward asymmetry, the rapidity ratio and the associated production. We also present two approaches to correct the Forward-Backward Asymmetry, which is affected by the unknown initial quark direction in the proton-proton collision. The study is performed for six different Z' models, using Monte Carlo events and a fast detector simulation. It is shown that the models studied here are distinguishable for a Z' mass of 1 TeV after one year of data taking in high luminosity.
