Description
Finite Unified Theories (FUTs) are N=1 supersymmetric Grand Unified
Theories that can be made all-loop finite. The requirement of
all-loop finiteness leads to a severe reduction of the free parameters
of the theory and, in turn, to a vast number of predictions. Here
SU(5) FUTs are investigated in the context of low-energy
phenomenology observables. We present a detailed scanning of these
FUTs, including theoretical uncertainties at the unification scale and
applying all phenomenological constraints. Taking into account all
low-energy restrictions, such as the anomalous magnetic moment of the
muon, b physics observables, bound on the lightest Higgs boson mass
and the constraints from cold dark matter density, we can
discriminate between different interesting models. We present the
predictions of the allowed parameter space for the Higgs boson sector
and the supersymmetric particle spectrum of the model that survives
the imposed constraints.
