Abstract

We study how the exotic particles and supersymmetric partners would affect the discovery limit at the Tevatron and LHC for neutral gauge bosons in generic E6 models. We examine the Z′ decay in the extreme case that all of the particles are massless, then consider how the masses of nonstandard model particles will affect the discovery limit. We also calculate the discovery limit for a supersymmetric E6 model with a secluded sector as a concrete example of a model with a definite set of exotic particles. Its discovery limit is small compared with other E6 models due to the U′(1) charge assignment.
