Distinguishing among Technicolor/Warped Scenarios in Dileptons

TL;DR

This paper explores how dilepton searches can distinguish between different models of dynamical electroweak symmetry breaking, specifically Technicolor and Warped scenarios, by analyzing resonance features in collider data.

Contribution

It introduces a method using invariant mass spectrum and charge asymmetry to identify the structure of new spin-1 resonances in various strong/warped symmetry breaking models.

Findings

Different models produce distinct resonance signatures.

Dilepton data can reveal the parity and isospin of resonances.

Specific features reflect the underlying electroweak symmetry breaking structure.

Abstract

Models of dynamical electroweak symmetry breaking usually include new spin-1 resonances, whose couplings and masses have to satisfy electroweak precision tests. We propose to use dilepton searches to probe the underlying structure responsible for satisfying these. Using the invariant mass spectrum and charge asymmetry, we can determine the number, parity, and isospin of these resonances. We pick three models of strong/warped symmetry breaking, and show that each model produces specific features that reflect this underlying structure of electroweak symmetry breaking and cancellations.
