Invisible $Z\prime$ as a probe of extra dimensions at the CERN LHC

Abstract

A class of extra dimensional models with a warped metric predict tunneling of a massive particle localized on our brane and escaping into additional dimensions. The experimental signature of this effect is the disappearance of the particle from our world, i.e. the particle invisible\to invisible decay. We point out that measurements of ZinvisibleZ\prime \to invisible decay width of a new heavy gauge boson ZZ\prime at the CERN LHC can be effectively used to probe the existence of large extra dimensions. This result enhances motivations for a more sensitive search and study for this decay mode and suggests additional direction for testing extra dimensions in collider experiments.
