The Lepton-Gluon Portal Beyond Lepto-Gluons

TL;DR

This paper investigates models with exotic states interacting via a lepton-gluon portal, analyzing effective operators up to dimension 6 and some dimension 7 operators, to explore collider signatures and production modes.

Contribution

It introduces a comprehensive study of lepton-gluon portals with new operators, expanding the understanding of exotic states and their collider phenomenology beyond traditional lepto-gluon interactions.

Findings

Effective operators up to dimension 6 are classified.

Potential collider signatures for exotic states are identified.

Single-production modes at colliders are analyzed.

Abstract

We explore models where single new exotic states interact with the Standard Model through an asymmetric Standard Model portal with couplings to at least one gluon and one lepton. We consider the complete set of effective operators up to dimension 6, and examine a few additional dimension 7 operators that contain interesting field content or potential collider signals. The lepton-gluon portal allows access to exotic states with an interesting range of SU(3) and SU(2) quantum numbers. Finally, we explore potential single-production modes and their phenomenological signatures at colliders.
