Interpretations of anomalous LHC events with electrons and jets

TL;DR

This paper proposes that pair production of vector-like leptons decaying into electrons and jets could explain recent CMS excess events, providing a plausible new physics interpretation.

Contribution

It introduces a new interpretation involving vector-like leptons to explain CMS excess events with electrons and jets.

Findings

Resonant pair production of vector-like leptons matches CMS data distributions.

The proposed model offers a realistic new physics explanation for the observed excesses.

The interpretation aligns with current collider constraints.

Abstract

The CMS Collaboration has recently reported some excess events in final states with electrons and jets, in searches for leptoquarks and $W'$ bosons. Although these excesses may be due to some yet-to-be-understood background mismodeling, it is useful to seek realistic interpretations involving new particles that could generate such events. We show that resonant pair production of vector-like leptons that decay to an electron and two jets leads to kinematic distributions consistent with the CMS data.
