Coloron-assisted Leptoquarks at the LHC

TL;DR

This paper proposes that a heavy coloron decaying into leptoquarks can explain multiple observed excesses in CMS data, predicting a distinctive edge in the m_T distribution at around 2.1 TeV.

Contribution

It introduces a model where coloron-assisted leptoquark production accounts for observed anomalies and predicts a specific kinematic feature in the data.

Findings

Explains CMS excesses with a 2.1 TeV coloron and 550-650 GeV leptoquarks.

Predicts an edge in the m_T distribution at 2.1 TeV.

Provides a unified explanation for multiple experimental deviations.

Abstract

Recent searches for a first-generation leptoquark by the CMS collaboration have shown around 2.5 sigma deviations from Standard Model predictions in both the eejj and e nu jj channels. Furthermore, the eejj invariant mass distribution has another 2.8 sigma excess from the CMS right-handed W plus heavy neutrino search. We point out that additional leptoquark production from a heavy coloron decay can provide a good explanation for all three excesses. The coloron has a mass around 2.1 TeV and the leptoquark mass can vary from 550 GeV to 650 GeV. A key prediction of this model is an edge in the total m_T distribution of e nu jj events at around 2.1 TeV.
