Finite theories after the discovery of a Higgs-like boson at the LHC

Finite Unified Theories (FUTs) are N=1 supersymmetric Grand Unified Theories (GUTs) which can be made finite to all-loop orders, based on the principle of reduction of couplings, and therefore are provided with a large predictive power. Confronting the predictions of SU(5) FUTs with the top and bottom quark masses and other low-energy experimental constraints a light Higgs boson mass in the range Mh∼121-126 GeV was predicted, in striking agreement with the recent discovery of a Higgs-like state around ∼125.7 GeV at ATLAS and CMS. Furthermore the favoured model, a finiteness constrained version of the MSSM, naturally predicts a relatively heavy spectrum with coloured supersymmetric particles above ∼1.5 TeV, consistent with the non-observation of those particles at the LHC. Restricting further the best FUTʼs parameter space according to the discovery of a Higgs-like state and B-physics observables we find predictions for the rest of the Higgs masses and the s-spectrum.
