Description
We study Finite Unified Theories (FUTs) in the context of low-energy
phenomenology observables. The realistic FUTs we have studied all need
or imply discrete symmetries to be all-loop finite. We present a detailed scanning of
all-loop finite SU(5) FUTs, where we include the theoretical uncertainties at the unification scale and then apply several phenomenological constraints. Taking into account the restrictions from
the top and bottom quark masses we can discriminate between different models.
Including further low-energy constraints such as B physics observables, the bound on the
lightest Higgs boson mass and the cold dark matter density, we determine the
predictions of the allowed parameter space for the Higgs boson sector and the
supersymmetric particle spectrum of the selected model.
We present a similar analysis for SU(3)^3 FUT models, where the theories
are finite if and only if they have three generations.
