“…In the see-saw scenarios, experimental data can be fitted by extending the MSSM with renormalizable interactions. We consider type-I see-saw, in which neutrino masses of the order of 0.1 eV can be obtained introducing additional singlet RH neutrino at the 10 13 GeV scale. This mechanism can appear naturally in GUTs without affecting the running of the gauge couplings and, therefore, their unification.…”

“…At this scale it is possible to postulate that the SU(3) c xSU(2) L xU(1) Y arises after the breaking of a higher symmetry that unifies the three interactions and acts from M GUT to a scale M X where gravity also unifies with the other interactions. Enhancing the minimal SUSY extension of the SM with a GUT theory [10] can provide a framework to analyse the recent LHC results and dark matter searches [11,12,13]. In addition, if the theory is complemented with a mechanism to explain neutrino flavour oscillations [14] , the models will predict flavour violation also in the charged sector [17,18,19,20,21,22].…”

We perform an analysis of the predictions of several supersymmetric Grand Unified Theories (GUTs) for Dark Matter and the LHC and compare the results with a possible Lepton Flavour Violating (LFV) signal, when the models are extended with a see-saw mechanism to explain neutrino data. We study unified theories based on SU(5), flipped SU(5) and SU(4) c SU(2) L SU(2) R , enhanced with a Type-1 see-saw mechanism. Each GUT predicts different Dark Matter (DM) scenarios, which can be used to classify the resulting SUSY predictions and confront them with experimental searches. Our results indicate that LFV is a powerful tool that complements LHC and DM searches, providing significant insight into the sparticle spectra and neutrino mass parameters in different models.
