AbstraktAbstract
We study effects of the scale-invariant hidden sector, the unparticle, proposed by Georgi, on top spin correlation at the Large Hadron Collider. Assuming no flavor-changing interaction between the unparticles and the standard model particles, the top-antitop quark pair production process arises through virtual unparticle exchanges in the s channel, in addition to the standard model processes. In particular, we consider contributions of scalar and vector unparticles and find that these make sizable deviations of the top spin correlation from the standard model one.
