Discriminating between technicolor and warped extra dimensional model via pp $\to$ ZZ channel

TL;DR

This paper proposes a method to distinguish technicolor models from warped extra-dimensional models by analyzing the angular distribution of Z bosons in the pp → ZZ → 4 leptons process, leveraging differences in their production mechanisms.

Contribution

It introduces a novel approach using angular analysis of Z bosons to differentiate between technicolor and warped extra-dimensional models in collider experiments.

Findings

Distinct angular distributions enable model discrimination.

The method effectively distinguishes between different strongly-coupled theories.

Analysis is applicable to the pp → ZZ → 4 leptons channel at colliders.

Abstract

We explore the possibility to discriminate between certain strongly-coupled technicolor (TC) models and warped extra-dimensional models where the Standard Model fields are propagating in the extra dimension. We consider a generic QCD-like TC model with running coupling as well as two TC models with walking dynamics. We argue that due to the different production mechanisms for the lowest-lying composite tensor state in these TC theories compared to the first Kaluza-Klein graviton mode of warped extra-dimensional case, it is possible to distinguish between these models based on the angular analysis of the reconstructed longitudinal Z bosons in the $pp \to ZZ \to $ four charged leptons channel.
