Gauge Couplings Evolution from the Standard Model, through Pati–Salam Theory, into E₈ Unification of Families and Forces

Abstract

We explore the potential of ultimate unification of the Standard Model matter and gauge sectors into a single E8 superfield in ten dimensions via an intermediate Pati–Salam gauge theory. Through a consistent realisation of a T6/(Z6×Z2×Z2) orbifolding procedure and renormalisation group evolution of gauge couplings, we establish several novel benchmark scenarios for New Physics that are worth further phenomenological exploration.
