Abstract

The perfect fit of the matter fields of the Standard Model (SM) into the SU(5)SU(5) multiplets has strongly supported the idea of the Grand Unified Theory (GUT) for decades. In this paper, we discuss a novel framework which explains why the SM matter fields form the apparently complete SU(5)SU(5) multiplets. In the new framework, the apparent matter unification inevitably results from chiral SU(5)SU(5) gauge theory even if the quarks and leptons are not embedded into the common SU(5)SU(5) multiplets. We call this class of models the "fake GUT". The novel phenomenological prediction of the fake GUT is more variety of the nucleon decay modes than the conventional GUT, which reflects the rich structure of the origin of the matter fields.
