High-dimensional Z' phenomenology at hadron colliders

TL;DR

This paper explores the complex behavior of a higher-dimensional Z'-boson coupled to hypercharge, affecting its detectability at colliders and analyzing the parameter space for potential observation at Tevatron and LHC.

Contribution

It introduces a novel phenomenological model of a Z'-boson with a non-trivial spectral density due to higher-dimensional mixing, impacting collider detection strategies.

Findings

Detection prospects are reduced due to spectral density effects.

Parameter ranges for collider study are identified.

Production cross sections via Drell-Yan are analyzed.

Abstract

We study the phenomenology of a Z'-boson field coupled to hypercharge. The Z' propagator has a non-trivial K\"all\'en-Lehmann spectral density due to the mixing with a higher dimensional inert vector field. As a consequence detection possibilities at hadron colliders are reduced. We determine the range of parameters where this field can be studied at the Tevatron and the LHC through its production cross section via the Drell-Yan mechanism.
