Resumen:
First indications for physics beyond the SM, such as neutrino masses and dark matter, have attracted considerable attention. This thesis focuses on neutrinos in models derived from Grand Unified Theories (GUTs). Supersymmetric and nonSupersymmetric realizations are studied. In the paper "Supersymmetric mass spectra and seesaw type-I scale" a numerical and analytical analysis of possible ILCLHC experimental data was done, identifying the parameter region in which pure CMSSM and CMSSM plus Seesaw Type-I might be distinguishable. Considering that neutrino masses could successfully be explained in GUTs, in particular SO(10), in the paper "Supersymmetric SO(10) -inspired GUT's with sliding scales"supersymmetric models with extended gauge groups at intermediate LR scales where constructed, all of which are inspired by SO(10) unification. Analyzing some special combinations of the SUSY soft terms, it was shown that future LHC data could contain information about the LR scale. Reconsidering the possibility to explain unification in non-SUSY theories, in the paper "LHC-scale left-right symmetry and unification" a list of non-SUSY models which unify equally well or better than the MSSM was found. These models are interesting from the phenomenological point of view: they can explain CKM and also obey proton decay limits while giving testable phenomenology at the LHC. Finally, we briefly explored the DM problem, searching for a consistent explanation of the DM candidate in the framework of LR nonSUSY SO(10) GUT models Considering the possible information that future Baryon Number Violation experiments might give for proton decay and GUTs, in the paper "Witten's mechanism in the flipped SU(5) unification" an analysis of Witten¿s mechanism within flipped SU(5) was done. Interesting relations between neutrino parameters and proton decay partial.
