Radiatively Induced Fermi Scale in Grand Unified Theories

Presented by Dr. Tommi ALANNE


We propose a Grand-Unified-Theory framework [arXiv:1511.01910], where the hierarchy between the unification and the Fermi scale emerges radiatively. As a concrete example, we study a Pati-Salam-type unification scenario, where the SM scalar sector is replaced by an SU(4)-symmetric one. In this scenario, the observed Higgs particle is an elementary pseudo-Goldstone boson. We show that it is possible to construct a viable model where the unification scale is taken to be above the experimental bound, while the Fermi scale is generated radiatively. This scenario opens up interesting prospects for exploring a wide variety of open problems in particle physics, ranging from neutrinos to cosmic inflation.
