The minimal B-L model naturally realized at TeV scale

TL;DR

This paper demonstrates that a minimal B-L extended Standard Model, with classical conformal invariance and stability up to the Planck scale, naturally predicts TeV scale B-L breaking, a light singlet Higgs, and light right-handed neutrinos, with testable collider phenomenology.

Contribution

It shows that the minimal B-L model naturally realizes TeV scale B-L breaking and predicts light new particles, under assumptions of conformal invariance and high-scale stability.

Findings

TeV scale B-L symmetry breaking predicted

Light singlet Higgs boson is expected

Detectability at LHC and ILC discussed

Abstract

In a previous paper, we have proposed the minimal B-L extended standard model as a phenomenologically viable model that realizes the Coleman-Weinberg-type breaking of the electroweak symmetry. Assuming the classical conformal invariance and stability up to the Planck scale, we will show in this paper that the model naturally predicts TeV scale B-L breaking as well as a light standard-model singlet Higgs boson and light right-handed neutrinos around the same energy scale. We also study phenomenology and detectability of the model at the Large Hadron Collider (LHC) and the International Linear Collider (ILC).
