`Model Building in Grand Unified Theories'

Abstract: Grand Unified Theories are a very well motivated extension of the Standard Model,
but the landscape of models and possibilities is overwhelming, and different patterns
present rather distinct and unique phenomenology. We present in this work a way
to automatise the model building process, by considering a top-bottom approach that
constructs viable and sensible theories from a small and controllable set of inputs at
the high scale. By providing a GUT scale symmetry group and the field content, all the
possible symmetry breaking paths are generated and checked for consistency, ensuring
anomaly cancellation and Standard Model embedding. We emphasise the usefulness of
this process for various models such as a Supersymmetric SO(10) model, a non-SUSY
left-right symmetry model or a theory of GUT inflation.
