✦ Synopsis
In LHC physics we study the spin correlation of top-antitop pairs production to investigate the production mechanism of heavy quarks [1]. The s-channel process mediated by graviton Kaluza-Klein modes in ADD model with several extra dimensions [2] or in the Randall-Sundrum model with only one extra dimension[3] contribute to the top-antitop pair production and affects the resulting top spin correlations. We calculated the full density matrix for the top-antitop pair production. We find a sizable deviation of the top spin correlations from the Standard.
