Giulio Maria Pelaggi, Alessandro Strumia, Saverio Vignali
TL;DR
This paper proposes a TeV-scale extension of the Standard Model based on a trinification gauge group, where all couplings can be extrapolated to infinite energy, addressing the Higgs mass naturalness problem.
Contribution
It introduces a realistic trinification model with three fermion generations and extra fermions, demonstrating asymptotic freedom for all couplings.
Findings
All gauge, Yukawa, and quartic couplings are asymptotically free.
The model is consistent up to infinite energy scales.
Addresses Higgs mass naturalness problem.
Abstract
Motivated by new ideas about the Higgs mass naturalness problem, we present realistic TeV-scale extensions of the Standard Model, into the gauge group SU(3)_L x SU(3)_R x SU(3)_c, such that all gauge, Yukawa and quartic couplings can be extrapolated up to infinite energy. Three generations of chiral fermions and Higgses are needed, as well as some extra fermion.
