Realistic GUT Yukawa couplings from a random clockwork model

Abstract We present realistic models of flavor in SU(5) and SO(10) grand unified theories (GUTs).The models are renormalizable and do not require any exotic representations in order to accommodate the necessary GUT breaking Data Cable effects in the Yukawa couplings.They are based on a simple clockwork Lagrangian whose structure is enforced with just two (one) vectorlike U(1) symmetries Quick connect in the case of SU(5) and SO(10) respectively.The inter-generational hierarchies arise spontaneously from products of matrices with order one random entries.
