Contact Interactions and Resonance-Like Physics at Present and Future Colliders from Unparticles

TL;DR

This paper explores how unparticle physics from high-scale conformal theories can produce distinctive contact interactions and resonance-like signals at colliders like the Tevatron and LHC, potentially observable in Drell-Yan processes.

Contribution

It introduces the concept of unresonance structures arising from unparticle exchange, providing a novel signature for detecting unparticle physics at colliders.

Findings

Unparticle exchange can produce contact interaction signatures.

Unresonance-like structures may be observable at Tevatron and LHC.

Unique signatures can help identify unparticle physics with sufficient data.

Abstract

High scale conformal physics can lead to unusual unparticle stuff at our low energies. In this paper we discuss how the exchange of unparticles between Standard Model fields can lead to new contact interaction physics as well as a pseudoresonance-like structure, an unresonance, that might be observable at the Tevatron or LHC in, e.g., the Drell-Yan channel. The specific signatures of this scenario are quite unique and can be used to easily identify this new physics given sufficient integrated luminosity.
