摘要:In the Randall-Sundrum model, we study top-antitop pair production and top spin correlations at
the Large Hadron Collider. In addition to the Standard Model processes, there is a new contribution
to the top-antitop pair production process mediated by graviton Kaluza-Klein modes in the
s-channel. With a reasonable parameter choice in the Randall-Sundrum model, we find a sizable
deviation of the top-antitop pair production cross section and the top spin correlations from those
in the Standard Model. In particular, resonant productions of the graviton Kaluza-Klein modes
give rise to a remarkable enhancement of such a deviation.
