Abstract: Finite Unified Theories FUTs are N=1 supersymmetric Grand Unified Theoriesthat can be made all-loop finite. The requirement of all-loop finiteness leadsto a severe reduction of the free parameters of the theory and, in turn, to alarge number of predictions. Here SU5 FUTs are investigated in the context oflow-energy phenomenology observables. We present a detailed scanning of theseFUTs, including theoretical uncertainties at the unification scale and applyingall phenomenological constraints. Taking into account the restrictions from thetop and bottom quark masses, we can discriminate between different models.Including further low-energy constraints such as $B$ physics observables, thebound on the lightest Higgs boson mass and the cold dark matter density, wedetermine the predictions of the allowed parameter space for the Higgs bosonsector and the supersymmetric particle spectrum of the model.
