Abstract
In this paper, we construct a model based on a flipped SU(5) partial grand unified theory, within the framework of the Randall–Sundrum (RS1) proposal. Breaking of [Formula: see text] is achieved using a bulk scalar field in the 10 of SU(5), Φ, which gains a vacuum expectation value <Φ> ~ 3 × 1015 GeV . We are able to retain the successes of the [Formula: see text] phenomenology, specifically the confinement of all fields to the smallest (1, [Formula: see text], and 10) representations of SU(5). We derive the beta functions, and point out some constraints on bulk matter content implied by the runnings (and positivity) of the five-dimensional coupling. Finally, we comment on baryon decay and show the fine-tuning problem required to prevent an exponentially short proton lifetime.
