Low-energy phenomenology of superstring-inspired E₆ models

In this report we survey the low-energy phenomenological implications of superstring-inspired E₆ models. The motivation for such models is reviewed. New particles including new gauge bosons, exotic fermions, Higgs bosons, and their superpartners are expected to exist in models of this type. We summarize the present experimental limits on these particles from both accelerator and non-accelerator data. Techniques for producing these new particles directly at existing and planned colliders as well as for searching for their indirect effects are examined in detail. Other phenomenological implications of such models are also reviewed.
