SPIN IDENTIFICATION OF RANDALL-SUNDRUM GRAVITON INPROTON-PROTON COLLISIONS AT LHC WITH 8 TEV AND 14 TEV

Abstract

New physics models, widely discussed in the literature, predict the existence of new heavy resonances with mass above 1 TeV that can possibly be observed at the Large Hadron Collider (LHC). These resonances, predicted by different nonstandard models can generate peaks with the same mass and same number of events under the peak. In this case, spin determination of a peak becomes crucial in order to identify the relevant new physics scenario. Here we discuss a possibility for spin identification of spin-2 Randall-Sundrum graviton excitations against spin-1 heavy neutral gauge bosons Z' and scalar heavy bosons in Drell-Yan dilepton and diphoton events at the LHC at √s = 8 TeV and 14 TeV by using a center-edge asymmetry.
