Using final state pseudorapidities to improve s -channel resonance observables at the LHC
We study the use of final state particle pseudorapidity for measurements of s-channel resonances at the LHC.

| description | 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 center-of-mass frame, possibly using a center-edge asymmetry measurement, A{sub CE}. In addition, forward-backward asymmetry measurements, A{sub FB}, can be used to distinguish between models of extra neutral gauge bosons. In this article 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{sub FB} and A{sub CE} for several representative models. |
