Abstract: The Standard Model correctly describes all interactions at and below theelectroweak scale. However it does not explain the peculiar pattern of quark,lepton and neutrino masses. Also charge quantization is not understood. Theseare well known motivations to go beyond the Standard Model and to build a GrandUnified Theory. This extension has several good predictions but the protonlifetime is huge compared to similar weak decays. This hierarchy problemsuggests two possible extensions of the standard quantum field theory: a nonlinear version of the Schroedinger functional equation and Third Quantization.We will make a comment on the safety of collider physics in the context of thenon linear extension of QFT.
