In this article we discuss the different kinds of experiments which can be explained in terms of neutrino oscillations. As a consequence of this neutrinos have to massive. But the oscillation data cannot fix the ν mass matrix totally. By considering the neutrino as a Majorana particle and using the information obtained the by search for 0νββ, we extracted upper limits on the elements of the ν mass matrix by using the upper limit of the averaged Majorana neutrino mass. To describe now massive neutrinos we considered the Rp-MSSM. We constructed a mass matrix within this model where all three neutrinos can be massive. By comparing the so found theoretical mass matrix with the extracted phenomenological bounds we extracted stringent limits on the trilinear coupling constants λi33(′). By imposing an additional horizontal U(1)x flavor symmetry we were able to reduce the number of parameters in out model drastically. We could by comparing the theoretical and phenomenological mass matrix determine the scale on the phenomenological side and the remaining coupling constants on the theoretical side. This leads to a unique scenario for the neutrino masses within this framework. The averaged Majorana neutrino mass in this model was found to be approximately 0.01-0.4 eV. This region will be explored in the near future by 0νββ experiments (e.g. the GENIUS experiment).
