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

Summary, in English

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