Unified explanation of the $eejj$, diboson and dijet resonances at the LHC

TL;DR

This paper proposes a minimal left-right inverse seesaw model at TeV scale that explains multiple LHC resonance excesses, predicts gauge coupling unification, and suggests dark matter candidates, with testable predictions for dilepton event ratios.

Contribution

It introduces a minimal non-supersymmetric left-right inverse seesaw model that unifies gauge couplings and explains LHC resonance excesses with testable predictions.

Findings

Explains LHC excesses with a $W_R$ around 1.9 TeV.

Predicts gauge coupling $g_R \\simeq 0.51$ at TeV scale.

Identifies dark matter candidates among $SU(2)$-triplet fermions.

Abstract

We show that the excess events observed in a number of recent LHC resonance searches can be simultaneously explained within a minimal non-supersymmetric left-right inverse seesaw model for neutrino masses with $W_R$ mass around 1.9 TeV. We further show that the minimal TeV-scale particle content that leads to gauge coupling unification in this model predicts $g_R\simeq 0.51$ at the TeV-scale. The extra color-singlet, $SU(2)$-triplet fermions required for unification can be interpreted as the Dark Matter of the Universe. Future measurements of the ratio of same-sign to opposite-sign dilepton events can provide a way to distinguish this scenario from the canonical cases of type-I and inverse seesaw, i.e. provide a measure of the relative magnitudes of the Dirac and Majorana masses of the right-handed neutrinos in the $SU(2)_R$-doublet of the left-right symmetric model.
