Mass Generation in the Standard Model

A proposal of mass generation in the Standard Model (SM) is presented, based on the idea that the violent fluctuations of quantum gravity at the Planck scale plays a nature regulator for the SM with fundamental length a_p∼10^-33cm, thus gauge invariant four-interactions are necessary due to the 'no-go' theorem of Nielsen and Ninomiya, forbidding a sensible formulation of the usual electroweak action on a such 'Planck lattice'. We present that for certain values of the new four-fermion couplings a spontaneous violation of SM chiral symmetry emerges which (i) avoids the 'no-go' theorem, (ii) produces a t ̅t condensate model without appearance of the low-energy Higgs boson. The mass generation of other fermions and intermediate gauge bosons, are briefly discussed.
