Abstract
TeV-scale seesaw mechanisms are interesting due to their potential testability at existing collider experiments. Herein we propose an E-inspired model allowing a TeV-scale pseudo-Dirac singlet neutrino seesaw mechanism with naturally sizeable Yukawa couplings of . The model also contains new U(1) gauge interactions (and associated bosons with which the singlet neutrinos can be produced at colliders), typically long-lived colour triplet fermions, SU(2) doublet fermions, and a complex scalar - potentially all at the TeV-scale. Additionally we identify three possible explanations for the 750 GeV di-photon excess.
