We adopt in this thesis a new approach by assuming a set of H-charges that\ngive rise to a self-consistent model of R-parity breaking and baryon-number\nviolation. As a consequence of our H-charge assignments, it is not possible\nto generate a Majorana mass term for left-handed neutrinos. However, a neutrino\nDirac matrix can be built after the introduction of right-handed neutrinos with\nproper H-charges. We also show that by adding a second flavon field with\nfractional charge, it is possible to build a Majorana neutrino mass matrix. In\nboth cases an anarchical matrix. The consequences for collider physics are\nmentioned. We will generalize the mechanism of obtain R--parity from an\nhorizontal symmetry to the context of SU(5) SUSY + widehatN, and\ncomputable group theoretical coefficients that, at leading order, determine the\nstructure of the neutrino mass matrix in a parameter independent way.\n
